Umm, well, the easy way to remove the tongues from the practice list is to go into skills.dat and delete them.
As for the detailed chracter creation code..I've seen it done many times, and in many ways. However, the only true way I found to do it without bugs was to rip it. I took mine from the SW:FotE code base. If you can't find a GOOD snippet for it else where, try ripping it from a similar code base that has it.
Sorry for being a lack of help...I'm an SWR user so I don't deal to much with SMAUG and AFK.
