Server Change help

[Cassieze]

Hello everyone! There are a few modifications I am looking to make to my server but after searching for a while I am not sure how to do it.
I am using Underfoot Client and PEQ revision 2506

1.) When I go to crushbone I want new orc models. 
-If I do texture 1-12 they will work just fine. 
-When I do #npcedit texture and repop the zone, any models that contain armor lose their armor. (They retain their color)
-ork,ork is in my crushbone_chr.txt

How do I make them retain their texture?

2.) I want bots to only be Warrior, Monk, Rogues
-I have implemented bots via the questsystem with the Aediles Thrall, but that only limits the maximum number of bots.
-I am assuming edits to bot.cpp have to be made. Since this is a source file I am not sure if text editing adds this to server (I'm guessing not). 
So how would I go about completing this?
-Also if possible how would I add another race to the list (Gnomework)

3.)I want to make ranger the only class available to play.
-I know character create combinations exist but is there a way to make it so when they create the character their only option is ranger?
-I currently have an npc change class upon hail if not a ranger

4.) Is it possible to mix and match aas?
-also I want to remove veteran reward aas
-possibly make all aas available

Thanks in advance
