Not sure, I don't rip models so I can't help you about the missing textures. For the various parts, just import them into the one scene in your 3d package and export to ASE or MD3. Just make sure none of the parts are over 1,000 verts.
if you send me the textures I'll examine them and figure out what they are, could be normal maps but a normal map woudl usually be purplish and not turqouise. So I'd expect it's a combination of Spec, Gloss and AO.
