Drop Adv. Proton Torpedoes entirely. They're only good in lists that are designed around them.
Expert Handling is a mediocre Elite card, I would dump that. Replace Shield Upgrade with Engine Upgrade - the boost action is very valuable on a PS9 large ship.
Beyond that... sort of depends on what upgrade cards you have available. From the upgrade cards you listed, I'm guessing you have access to the Millennium Falcon, Kihraxz, B-Wing and Core Set, so I would make the specific suggestion of:
Han Solo (46)
Veteran Instincts (1)
Chewbacca (4)
Nien Nunb (1)
Engine Upgrade (4)
Millennium Falcon (1)
Luke Skywalker (28)
Predator (3)
Proton Torpedoes (4)
R2-D2 (4)
Shield Upgrade (4)
Total: 100

Proton Torpedoes are kind of crap, but a fluffy choice (drop Nein Numb if you want pure, unadulterated fluff). You won't win tournaments, but this should be perfectly serviceable in a casual game.
