about the Battledroid model, I'd suggest using the version made by Prophet. I think it's the best modeled version out there and it has the most skin options as well. You might have more luck contacting that guy as well.
a quote from the readme file:
You may distribute this model file, provided this readme and the zbattledroid.pk3 file remain intact. Whenever possible I\'d like to be notified if you\'re distributing this, but I don\'t mind. It may not be edited in any way or used for any purpose other than a user-made modification for Jedi Knight II: Jedi Outcast without asking me first. I have skin maps available to anyone who wishes to skin it.
