Yeah looking at your roster you have a couple ways you can go. Finish Bossk, Jango, Boba, Dengar and whoever else, I would suggest IG88 as you need his ship for the falcon. Or you can switch gears and go the JKR route, however with out Hoda or GK it might be best to round out a CLS team over the next 4-6 months and have a complete team (CLS, Chewie, 3p0, Threepio and Chewie and RHan). You can also slow farm ewoks while you go for chewie so that you can immediately go to the 3p0 event after.
What's your end goal? Are you wanting to work towards a specific end game toon? Or just build depth and see where it goes?
I'm sure others will have much better advice so stay tuned.
