Lookin good.

I'm not sure how Wings3D works, but in Lightwave...
create your UV's...
maximize an orthographic view of the UV's...
take a screen shot(prt scrn works ok, but there are plugins)...
paste it into photoshop...
crop it so the only thing that shows is the ortho window...
Save it and test it before you do a bunch of work on the image. I always test it with the UV lines still visible. That way, you can easily tell if the UV's are lining up the way they are supposed to because you are actually mapping a snapshot of the uvmap.

I hope that makes sense to ya... I don't know of any tutes for Wings, or else I'd post a link. Sorry.
