AHHH, I remember when I encountered this problem. Basically, what you have to do is something called mapping. Since your UVs are actual cordinates, you need to organize them into something you can see. I highly recomend mckenly's other texturing tutorial. (on his .net site). It goes through basic planar mapping, and it gives alot more detail than anyone could in just text. It really is quite simple, its just hard to make it look good (texturing that is).

Here is the link to his website.

Edit: You will need some sort of .rar uncompressor. And it is under his tutorials -> modeling -> polygon texturing section.
