I can only think of two: Royler Gracie - Submission Grappling (I think it's called that) Eddie Bravo - Jiu Jitsu Unleashed
Mark Hatmaker has published two good books on submission wrestling, Killer Submissions and (of course) More Killer Submissions. I have a couple of his DVD's also, they are also very good. No gi wrestling seems to be the thing now in MMA, very few guys are winning with the gi. If you goggle Matt Hatmaker you'll get his web site.
