I'm a bit confused.
Do you need help with a preset, textures, etc? Please explain more.~ c:
If you need all three, I'd recommend looking here at the big tutorial list:

EDIT: I see you edited your post. c: With the meshes you downloaded, was there a file called a .mat? Without the .mat, textures will not show up. Same goes for the actual texture/picture. What objects did you download?
If it didn't come with the actual picture/texture, I'd refer to this:
