I wonder too about good UV map techniques and complete texturing process books. I am hoping Mike McKinleys book for the game artist will address some of my questions.

Here's a great book on lighting:
Digital Lighting & Rendering by Jeremy Birn.
Novices and intermediates will get the most out of this book.
It's not application speciffic, but it's better than that imho. It teaches lights, art and cinematography fundamentals. Highly recommended.

There's also a digital Texturing and Painting by Owen Demers in the same series. I dunno how the book is coz I haven't read it.
