The last time I made something proper in blender the whole model was done with nurbs things, I gave up when I found UV mapping a sod with blender's still awful interface though I can texture basic things at least
UV mapping on nurbs? I haven't done that, but I can assure myself that it'll be more confusing than with polygons at first sight. I only use nurbs for design works like cars. Cars are just so smooth that polygons won't do it even if it looks good. When you take a picture of a polygonal cars and then play with brightness/contrast, you'll see how much justice polygons do compared with nurbs.
I only UV mapped a cube and that was only when I finally learned how to UV map things, doing the same on nurbs is beyond my skill. I'm not a serious 3D modeller, I got blender because I wanted to try 3D but the interface confused me a great deal.
