Oh, regarding that reflective eye layer thing: I just wondered how to uv-map the eyes if I get rid of it and add a cornea instead. You'd want the sclera texture to blend nicely with the iris, but its normals to match the cornea's. Obviously, that's a bit easier to do when working with two complete layers, so maybe that's why some people use that technique. Just a speculation.
