er ahh. not sure if i get what you wanna do but if your asking about upmixing stereo to 5.1 there are multiple threads here about it. and yes you would make 6 wavs to work with. but we need more information to give you a real answer. i.e. what is your editing program? ect. most people would want to do a 5.1 track because well we are in an age of surround sound home theater. as for editing audio you will be limited on what sounds you can remove. as far as removing voices this only works on 5.1 where the center channel has voice only. and that is rare or never. what i would do is cut the parts you wanna use from your stereo track and save them separately to wav. from here womble mpeg wizard can upmix to 5.1. or do em in vegas. keep in mind upmixed audio is not going to have the panning effects of true surround. its basically just turning 2 channels into 6. if you are just talking about using music tracks from the soundtrack that shouldnt be too hard just upmix them to 5.1 and edit them in. lets here some more specific info on what you wanna do. a particular scene where you wanna use your soundtrack.
