changing models and sounds

[Dadalife]

Well... I have 2 questions... 1st one is about race to race swaps. So basicly when we do so, we change the base model, and because of that npcs of the changed race begin to look funny. So is there a way to change ur race without changing npcs look?
2nd question. Well, I changed the race, but DrF with roars of OrM makes my face look like :confused: Is there a guide to change the counds like we change models and textures of races? I tried it myself, but in MPQ files I found only sounds of strikes and receiving damage. And when I tried to change it like I did with race to race swaps it didnt work. Also can someone tell me where are the emotion sounds of the races in the MPQ files?
P.S. Sorry for my bad english
