Releasing Henderson was definitely a bad idea. You should have been able to trade Henderson for a solid player without a problem. He's good on both ends on the floor, and he's really athletic. If he develops a three-point shot, there's a good chance he could be a #1 or #2 option on offense.
The only problem I have with your lineup is that it is undersized. While that is likely to be the case for the real life Bobcats, I see Biyombo as a power forward and in 2k, it shouldn't be that hard to bring in a legit center. I think your best shot is to flip Crawford and a draft pick for a good center. The Bobcats are likely going to play Augustin and Walker in the same backcourt (yes I know that would be undersized), and I actually can't wait to see how that turns out. Augustin is great in 2k and shouldn't be buried in your bench like he was under Larry Brown.
This is what I can see happening (since you've already gotten rid of Henderson- bad idea, but I like the addition of Crawford):
-starting lineup of: Augustin | Walker | Maggette | Thomas | the center you could get from trading Crawford (best case scenario would be Nene or Tyson Chandler or someone, but it's more likely it ends up being someone like Brendan Haywood or Chris Kaman, which still is a significant upgrade over the Bobcats' previous center)
-bench made up of: Diaw | Biyombo | trade off most of the remaining scrubs for expiring deals, draft picks, or young talent
Hope this helps.
