Also, just a heads up, Rhino is a nurbs-based modelling program, which means that the models made by it are so high poly it isn't feasible to use them in any current game engine. I'd suggest you try to learn gmax or the XSI mod tool (that comes with HL2, if you have it), as they are both free and watered down versions of 3ds max and XSI, respectively.
I've heard good things about blender, but have never used it myself.
