Please Critique My Game/Win

1. e4 e5 2. Nf3 Nf6 {Starting the Petrov Defense (C42)} 3. d4 {Moving into the Modern (Steinitz) Attack (C43) and detering Bb4. Black can transpose to the Philidor Defense with which my opponent is used to playing.} 3... exd4 {Black properly breaks symmetry.} 4. e5 Ng4 {Ne4 keeps the Knight working at full capacity and also guards g5.} 5. h3 Nxf2 {What is Black thinking? Is this a blunder??. . .How can Black have a natural win now? Nh6 is better.} 6. Kxf2 Nc6 7. Bf4 Bc5 8. Bd3 {Blocking a pawn while developing, preparing for defense, and making more room for my King, Queen and Rook. How can this be a bad move since it accomplishes all that at once?} 8...Nb4 {Perhaps, trying to remove a block to a discovered check.} 9. Nbd2 Nxd3 {Trades, however, can benefit White because of a surplus of power pieces.} 10. cxd3 d6 11. exd6 cxd6 12. Re1 Be6 {What do you do when you don't know a good move to play next?} 13. b4 Bb6 {Watching for 13... Bxb4 14. Qa4+ (Ke7, Kf8, or Qd7) 15. Qxb4} 14. Ne4 Bc7 15. Kg1 {Accounting for Black playing Qh4+ after I play Nxd4. No need to rush.} 15... Qd7 16. Nxd4 O-O 17. Be3 {Wishing I could play Qh5.} 17... f5 {I would not say that I accounted for Black playing f5 with my King and Bishop on the F file; fortunately, they are not.} 18. Nxe6 {I need to take the e6 Bishop before it gets to d5 aiming at my King side and blocking my possible Queen's access to Black's King from Qb3.} 18... Qxe6 19. Ng5 Qd5 {Why didn't Black try Qf6 looking to send an attack down the King side, if possible.} 20. Qb3 {Trying Qf3 left me with less pawns, and like Venda alludes in his post, enemy Queens can be a nuisance. So, Qb3 puts me one step closer to a win because Piece Trades can help White in this position. That doesn't mean I like having doubled pawns on the B file though.} 20... Qxb3 21. axb3 Rfe8 22. Bd4 Bb6 {Around move 23 is where I need to keep one of Black's Rooks off of the C file so that Black will not remove my Queen side pawns.} 23. Nf3 Rxe1 24. Rxe1 Kf7 {Black could have claimed the C file with his last Rook on this move.} 25. Rc1 {Fortunately, I get to shut down Black's use of the C file.} 25... Re8 26. Kf2 h6 27. Bxb6 axb6 28. Rc7+ Re7 {Does Black think he will draw or win by letting me trade for his last major power piece? Trading in this position can help White.} 29. Rxe7 {Black Resigns. . .Sources used for this game may include: http://www.365chess.com and http://www.eudesign.com/chessops/index.htm and http://www.chesslab.com} 1-0
