Lighting is not that important unless you want a specific atmosphere. Of course, IMBW. You can always add a light or two, just for fun. The imported skin has to have the texture set both on Diffuse and Ambient colours - up at the top. And then play with Diffusion and Ambience values in the second group. (Sorry, no pic, I'm not at home.) Specularity has to be set to a low value, otherwise you'll get a plastic look. I wouldn't set Reflection at all.
