You can get some updated rosters at my site. We have a guy that just posted his 9-5-05 rosters w/ all cuts, trades, etc. These are Xbox rosters. If you are looking for PC rosters, I'm sure there are some at maddenmania or maddenplanet.
LOL, I know the feeling. Gotta love these roster geeks, they make the game that much better. Although I miss my NFL 2K5 Rosters are coming in for that one as well.
