The medal in the middle is the Kalidor Cresent. You get it when you get over 3,000 bonus points in the Rebel TODs. You get advances in the medal when you get more bonus points (I don't know how many though) and no you don't get to fight Antan you, the game just ends at Endor. You can download various missions from over the internet though.
If you leap before you look, I'm not catching you sorry ass!
