[Adding Textures?]

I am rigging and editing a mesh that I imported from Google Sketchup in Maya. When I export the mesh, it has no textures, and when I look in the .zip that it came from (Exported through the .kcz method), I can't find any textures. However, I know that there are some in the mesh because when I open it in blender or upload the Sketchup-Exported version to second life, it is able to load textures.

 

How should I be able to apply textures? 

[Rigged mesh no joints or skin weights]

I am also getting the same problem with my Maya rigged avatar. The Skin weights and Joints option doesn't show up. I am new to mesh editing and rigging, so I have no clue how to do this. Would someone be able to take a look at the model and tell me what's wrong?
