I'm not really sure what we can offer you in a forum like this other than some places to go and study. The ChessGames.com link has a good collection of GM games you can go over.
Rybka 4 multiprocessor on an i7 quad core says that 13.g4 gives Black the advantage. 13. g4 hxg4 14. f4 Nc4 15. Bxc4 and with Rxc4 White's attack is going to fizzle, I think.
