Like the first game, there're some general classes of characters you know about:
Blaster - Fires ranged attack. Has wire hook to grapple. Default characters include any one with a gun. Customizable from the cantina station. Note the character with the revolver type weapon has the shoot dodge (and rapid fire) ability.
Jedi - Engages lightsaber melee attack. Has force powers. Can double jump. Default characters include Luke (Jedi), Yoda, Vader, and Kenobi. Customizable from the cantina station. Note saber color determines Force alignment for customizable characters, but the Maul head also affects alignment.
Dark Jedi - As Jedi but can affect Dark Side objects. Vader is default. Note saber color determines Force alignment for customizable characters, but the Maul head also affects alignment.
Ghost - As Jedi but enemy does not attack (as per disguise rule).
3PO - Droid 3PO can open 3PO doors and switches. Most useless character of your party, apart from opening doors. Unavailable as custom character.
R2D2 - Droid R2 can open R2D2 doors and switches. Hovers short distances (same as Fett's jetpack). Electric probe can also stun enemies. Unavailable as custom character.
Kid, midget or amputee - Can go through kid-tunnels to reach secret areas. Unlike the old class, this version can fire like the blaster class, but cannot do so when moving or jumping. Default characters are Wicket and the anonymous Ewok. This class is not available from custom mode.
Stormtrooper (Imperial) - Can go use Imperial doors and switches. This is part of the disguise factor. Note not all characters can use the disguise station. Available from the cantina station. Default character is Vader. More available from the shop.
Bounty Hunter - Can go use Bounty Hunter doors and switches, and may create a remote bomb for destroying shiny metal objects for extras. Default character is Leia (Bouush) and more can be found in the shop. This is also a part of the disguise factor. Note not all characters can use the disguise station. Unavailable from the customization mode.
There are several ships you operate in the game, each with a different number of proton torpedoes (or bombs) they can carry. For example, the Y-wing has a capacity of five, while the X-wing has a capacity of three.
Unless you have a good place to get bombs from (the bomb generators or enemies), save your bombs. In co-operative mode, both players may overlap same target, so fire in sequential order.
The AT-ATs are indestructable until you trip them using the tow cable. Once they are downed, tow a bomb from a bomb dispenser and blow it up. AT-ATs that are downed will revive like a Hammerite Undead from Thief Dark Project if enough time elapses.
Hint - Self Destruct Extra
Just thought I'd mention the self destruct isn't a completely useless extra. Though blowing up your droid may seem like a bad idea, it is worth noting you don't lose studs (from the act of self-destruct). This means that you could blow up to prevent losing studs from falling, or you can send your droid, which is usually ignored by enemies, into the middle of a bunch of them, and boom. If you opt for the invulnerability extra, it's kinda pointless entirely, but it's an option open to other players.

Gold Brick Awards
Aside from the Super Story and Bonus arches in the cantina (about 40 bricks), you can unlock LEGO City at 60 bricks and a money generator at 99 bricks.
If you want to buy all the shop crap using the multipliers, do yourself a favour and purchase the Score x2 cheat first, then slowly build up to the "30 million" 10x cheat.
The "30 million" is actually less than you think if you have the score cheats stacked and in effect, so the greatest amount of money you need to actually collect is 3 million (for the Score 4x cheat at 6 million). This is because for each stud you collect, it's multiplied by the score multiplier cheat.
By the time of the score 6x cheat, you will be collecting 24x the amount of money, making the score 8x cheat (at 20 million) cost considerably less (divide total by 24).
