Well, I guess since I am only allowed to state results here, and we are not allowed to work together at all:
I have been able to now extract all sound files from the paks, decrypt them, and then convert them over to mp3. So now I can just listen to all of them in Itunes, which is cool.
Now that all character sounds and stages music are taken care of, time to move on to meshes…
I guess I really need @rukizzel to clarify… am I even allowed to post something like the above?
