Boba Fett is a good choice, as is a young Han Solo film to start.
What I'm really pining for, eventually, is an Ashoka Tano film. She is so clearly the break out star of Clone Wars. The idea of Darth Vader having to find and kill his former apprentice, who he was very overprotective of, strikes me as very interesting. Remember Luke's "there is still good in him" speech? I'd like to think that as twisted as Vader becomes, he wouldn't kill his former apprentice.
In any event, should be fun. man, am I glad Lucas sold the rights to Disney, a company that knows what to do with these properties.
