You'll also want to take advantage of the vehicle tokens that are scattered around the levels. You'll be able to take advantage of A-Wings and AT-ATs if you're quick enough.
These vehicles are extremely powerful if they're used correctly. They can net you tons and tons of points over the course of a game.
AT-AT and AT-ST's are especially deadly early on in the game and you'd be smart to hop into one of them if you can.
