over at Talking the Talk we're working on Living Star Wars. It's a post-rebellion era game, and so far we're limiting ourselves to just the core book until we get some GMs and Players to join and vote in more books. In fact, I need some players right now for two games (hint hint, nudge).
Otherwise, the above books sound good. I'm so-so on Force Unleashed, if only because it seemed really bare for a lot of the advice. I see it as the early Rebellion era, with the exception that the PCs are creating the Rebellion (if they want to), or are fleeing the Jedi Purge.
The rules for organizations are good in that one, though. it's another form of reward/punishment by giving you points that add up to rank/regard in the organization: House Organa and the Bounty Hunters' guild are two notable examples. As a template for other groups, it'd help a lot. In fact, if you're raising help for the Rebels, have small tables that add up for different factions/planets: get X number of points and they'll give the Alliance a pile of ships or soldiers. if the players achieve enough, they strike a blow against the Empire and "win". This helps if the point is to run a lot of small missions around the galaxy, rather than just a BBEG showdown (which you can still do).
Personally, if you have the Core book you're fine. Starships is handy, as is Droids, simply from the point of equipment. Unless you're going to fight it, you don't need stats for it. If you have the Core book, you could theoretically make up all the non-monster stats you want, and droids, and maybe creatures (I don't remember if they also are in there).
