I have been running this list awhile now and am thinking its time to run it against tougher competition. I have had good success, using A's to bump.
Chewie: with Luke, title, anti-pursuit
Green Squad: Test, PLT, Wired, char, Stealth X2
Been debating AT instead of Stealth, but as often as I'm in close trying to block, Steath seems to work better.
Small tweaks for me would be to drop Luke for Gunner from the Falcon, then swap the SD's for AT's on the A-Wings and give the Falcon either:
Not stellar by any means, but a good chance to provide survivability to all ships with the second option. If SD has been more reliable, then perhaps keep the A-Wings unspoiled, use Gunner instead of Luke and maybe give Chewie Intimidation in case of any pile-ups that free your A-Wings.
You could make the A's into Crackshot-A's with adaptability.
Green squad: Crackshot, Adaptability, Test, Char x2 (Autothrusters optional)
Han Solo: Predator, C3PO, title, Luke (engine optional if you drop thrusters).
If you want to block with them mostly, you could skip autothrusters, to beef up your YT-1300.
The only problem I have with your current list is that it lacks punch. The crackshots + Han with luke will punch through a lot of dodgy aces. Personally I would go with engine on Han!
Thanks guys, those suggestions make sence. Most of my strat. is longevity. All three always have an evade token. I also tend to run in close for a knife fight, so I like chewie with his lower PS and no crits. I love the idea of 3P0, and want to work that in, If my neighbor will let me have his card 
As I am in range 1 ALOT the wired A's seem to actually pack more puch than you might expect. After the advice, my big question is to implement Draw their fire, or Intimidation on Chewie
