Well, Shatterstone beat me to getting the Master/Apprentice list up. No problem there, less typing for me

I'm not picky as to who your character goes with, but I won't give you any ideas on what the Masters are like(Both have very different focusses). Just as long as each group has 4.
Group fund? Go ahead. Though I'd expect it'd be best to group it with those who train under the same master. The Jedi Masters have things like training equipment, etc, so its not much of a problem with things like that.
As for group dynamic...the eight of you would know each other. The two Jedi Masters are very good friends, and have worked together(with all of you involved) many times during the Sith War. Of course, you'd obviously know the other three apprentices to your Master the best.
