You should definitely check out my roster update to the updated OSFMv2 Opening Day set that a few of the forum members updated with stances, equipment and pitches. The pitches were based on pitch f/x data from 2009 and early 2010. I have updated more than 95% of the pitchers based on their 2011 pitch f/x data.
On top of that, I've made tens of thousands of changes to attributes, faces, stances and deliveries. I've also included 37 draft picks.
You can quite a bit about of the details here:

Are you going to be playing a season or a franchise? If you play a season, every team is going to lose their minor league system and anyone not on the 40 man rosters. You're missing out on a lot if you play a season instead of a franchise.
Also, for the record, my set is a 25 man set so you will need to use Srudoff's spreadsheet to add the players back to the 40 man roster.
