A few quick thoughts. This is a pretty good team for someone getting started, and I would keep the nucleus. You've drafted more innings than you will need in any ballpark (ignore SIM's advice). You've got about 1500. You only need 1200-1250 in ballparks with a singles factor of 0, less in ballparks with negative singles factors and only 1300 or so in even the most offense-oriented parks like Coors and Atlanta Fulton County. Boogerlips has a nice analysis of innings needed for various types of parks in a recent thread . I'll try to bump it up, although I think it's intended for $80 MM leagues, not $100 MM.
Your pitchers also give up too many HR's. You'll be surprised at the extent to which guys like Gibson, Shantz, Carlton and Hall get rocked. I try to keep pitcher's ERC# under about 2.30 and HR/9 under 0.50 (way under 0.50) except for mops and special circumstances. SIM has a lot more bashers than these guys faced in an average game in RL. I would convert some of the long relievers with 75-100+ IP to guys with under 50 IP and low ERC# and low HR/9.
On the offensive side of the ledger, Joe Morgan and A-Rod may disappoint. They don't normalize terribly well and A-Rod in particular will get fewer HR's than you expect. Bonds and Bagwell should do well. If you have AAA players, I would get rid of all the scrubs for whom you paid over $200K. The AAA will perform better than the scrubs. You should definitely get rid of Julian Javier. You don't need his PA's at 2B, and he doesn't bring anything to the table either offensively or defensively.
Because your pitchers give up a lot of homers, I'm tempted to steer you to a homer-suppressing park even though that neutralizes your sluggers. You might consider a neutral park like Forbes Field or, if you want to capitalize on your high OBP but leave your HR's for the road, try parks like Dodger Stadium, League Park, PNC or Comerica that are conducive to your ability to get on base without bludgeoning your pitching staff with HR's.
