I agree that you could use a little more pop in your lineup -- Helton and Chavesz should be good for around 30hr, Bay could get you 25-30, and if healthy, Berkman can send them out. Utley has had a good spring, but who knows how he'll do over a full season. If you're going to make any moves, try to move a bit of speed (Rowand or Crisp) for a bit more power.
I like your pitching a lot. If Adams is closing, I'd play him over Gonzalez (though hold Gonz since Mesa will likely lose his closer role at some point this year). Kazmir is a nice gamble, but if he doesn't pan out, he'd be the first I dump to waivers.
Feel free to look at mine:
