Questions about PennMUSH (what it features by default?)

Ok, this topic has a tricky name. I shall explain.

My idea of the game I want to do is a mix of socializing but also I want a little built in snippet of sorts to have at least a battle system so people will win experience from slain certain mobs. I'm afraid that PennMUSH doesn't have a built in battle system of sorts (I'm ignorant of what PennMUSH features by default) but I think PennMUSH is enough flexible to allow some extra coding to make space for a battle system. Correct me if I'm wrong here.

Now my other questions (which I suppose are totally related to my lack of knowledge about what PennMUSH features by default - if you wonder if I ever played a MUSH, I don't, I'm aware that all the MUDs I played were all based on SMAUG, so, I has no clue *shakes head in shame*). First, mi ideas about the characters (which are pre-made and not created by the players themselves - they can create alternative characters but they are meant to control 2 main characters which comes from our RP community and those are predefined by the administrator by default):
About skills:

1. -Some characters are able to "fly" or "filter" through walls on a whim (though I hope to restrict this whim with stamina points so they don't use that endlessly and need to rest). Am I able to add "skills" to characters so they can use them while others has other "different named skills" which does the same (for example, one character can "Fly" directly but other character only can fly using a tool, hence the need to change the name of his skill but the effect is similar to the "Fly" of the other dude)?
2. -Some characters has what it can be called "Wizard" commands by default, for example, X and Y characters have the skill to teleport everywhere they remember by creating portals which others might want or might not want to cross (unless shoved inside but that is RP wise). These portals aren't temporal and only them can close them forever or reopen them. Is that possible?
3. -Regarding "Wizard" commands, X character has the skill of creating "rooms" or dimensions of her liking (she would be able to create them, add descriptions, items and put a "float" flag on them, and link that room or rooms to the "real world" by using the skill of Portals I mentioned previously. Is it possible to enable this "skill" only for this character?
4. -More "Wizard-esque" skills. 3 characters are able to create and destroy those items on a whim. I know those items would be totally owned and bound to them, despite they need to be able to give them to other characters (ie. giving a trenchcoat to another character so that this other character can wear it). You think it is possible to enable this?
5. -Randomly, 3 characters of ours are able to "make food", and basically, from a list of recipes, they should be able to bake/cook consumable items for themselves and the others around them (if the switch "kitchen/oven" is available). Not all characters are able to cook (and specially one of them cooks very BAD) so, I was wondering if was able to enable this skill only for these three characters.
6. -Another "Wizard-esque" skill (I think it is "wizard-esque" but I totally got the idea from the MUDs I played), one of the character is able to "morph" into other NPCs if she knows them (ie. cat, policeman, water elemental, etc). The trick is that she is able to morph into them and win their characteristics and skills by default on those NPCs (for example, if she morphs into a cat, she wins automatically the description of a default cat instead of her customized description, and also wins the skill of the cat, which is CLIMB, if you follow what I mean by that). She is able to unmorph at will (there is no time counter for her morphs), but upon unmorphing, she will lose all the previous gained skills derived from the morphing, so, technically an "undo" command. You think this might be possible?
7. -About learning skills... There is a possibility that a character reads a book, for example, about cooking, and thus winning the skill of cooking by just reading that book. This seems to don't be a great problem but I want to add a "MUD feature" to this learning, which basically is the % of success of that character to succeed on cooking. So, he/she might only be only able to bake burnt muffins (who no one wants to eat, yuck) but after reaching 25% of success, voilà, a recent baked appetizing muffin everyone will love to gnaw on. Now I think you see what I mean by pasting some MUD features into the MUSH since this % rating of success comes from several MUDs I played.

Battle System:
*First, I don't know if there is some kind of promp with health and others by default in PennMUSH (hence the name of the topic), but if it lacks of one, I believe we can work one and other things as follows - and I repeat, battle is very secondary on this game, but still a problem more than one character will face while RPing - also because more than one of these characters loves to duel between themselves, so, a duel system is on the order too D:*

• Amongst the characters, only a handful of them (who are the only ones able to wield certain weapon) can kill certain mobs which are too "magical" for regular power-less characters to be able to defeat. That means if a character doesn't wields certain weapons, its rate of success will be always 0 (ie. the mob will be inmune to the attacks of the character). This little "if character Y wields [X] item flagged as [magic], then all attacks hits - else, all attacks fail" idea, do you think it is implementable?
• The idea of characters being able to gain experience from mob slaying (even training dummies) then asks for the mobs and the players to have levels. Apparently the only idea behind gaining exp in this RPG is to reach the next level, thus all the basic STATS (STR, DEF, etc) increases in a pinch (not randomly but after a calculation depending of the character - I'm used to stat calculations and calculators, so, if a character is of the "speed type", DEX and VEL would increase on a bigger % chance than the rest of the stats each level up). This will also be rewarding since quest on areas too dangerous for low levels will be automatically open for the higher dudes to roam freely without fearing the mobs, and also enabling them to wield certain high end weapons, and being able to learn new high level "battle skills" which will be unlockable after reaching certain level. HIT rolls and DAM rolls will be also affected and that stuff, so, technically this looks like to port some SMAUG coding into PennMUSH (unless PennMUSH already has something else different built in - I hope this can be tweaked, correct me if I'm wrong).
• I don't know if this will be accepted, but, can a player pick up an object (ie. a chair from the room) and "smash" it over another player, causing some damage points (depending of the DAM roll) and even being able to incapacitate the other player temporally if the success of the hit is 100%? I never saw this on MUDs but I think that being able to pick up objects from the room and use them for different purposes forms part of the "socializing" (ok, smashing chairs upon the heads of people is not very sociable, but at least I want to give the game some kind of full interactivity which the players will need to explore by themselves). I forgot, the object will be destroyed after being "smashed", and it will respawn upon the departure of the characters (I suppose "if [players] in room = 0 then objects flagged as [smasheable] respawns".

By the moment, I have no more questions. Basically these are some of the ideas I want to implement inside the game by coding it accordingly. I'm already on XNA programming and learning another language will not be a very big problem for me. Still, I feel I'm a total newbie, but I has the patience and the time to learn what I can do with PennMUSH and what will be utterly impossible to make. Then is when advising and tips are very very welcome!

Sorry for the long post. Hope someone can help me to clear out these questions and point me what part of my ideas for the MUSH/MUD thing are OK to code and what of them would be impossible. I'm aware that my idea of my game is very "MUDdish", but SMAUG has too many things implemented on the battle system which needs to be heavily redone from 0 to adjust them to what I need. I only want to "rip" some bits of SMAUG and use them inside PennMUSH (or create an equivalent to them on PennMUSH "language") to customize my game, but, without killing all the features that PennMUSH already has (which then I come full circle here and I ask again: what features are on PennMUSH by default? - and I don't mean the ones which talks about the mail-box, the built in chat and such but about what players are "able" to do and that stuff - I need to remind you that I never played a formal MUSH, so, if some veterans from them can talk to me about their experiences inside MUSHes, I'm all ears).

Best regards. Advice and insight are welcome :)
