Isn't Boba 4*?
You got an amazing team. I'd build 55555, Phasma, Dooku, Sid, Rey, Lumi. You got such a great lineup. And Boba for the future (he's a wonderful Leader). Chewbacca, I've heard isn't great as he is starred up. Perhaps go with Finn, Poe, Han or Opress Savage.
5's is not good and I regret the resources that I put in to him. Work on these 5 first BUT you need good light and dark side squads and enough decent characters to get through GW so don't solely focus on these ones. I'd probably use Sid as leader.
