I'm creating a custom race mod, having problems.

Well, I'd recommend using Blender instead, it's freeware and has the same features you need.

This is a nice tutorial:

It also works for horns, tails and whatever.

I fear that I can't be your "teacher"

So just tell me where you encounter problems. Skin textures are edited with Photoshop or Gimp. I guess you can paint textures directly on the model but if aren't an expert you can use Gimp, and then install the plugin I talked about. There are a few files for a skin texture, but you probably only want to mess with the diffuse one.
