Go to Jabbas:
As you head up the path to Jabbas you kill some Jawas (always fun) and droids.
When you see the Jawa Sandcrawler go up to it's left side (as you are facing it) and force push it off the bridge. Work your way through the landslide while double jumping/dashing over the holes. Watch for Tusken Snipers as they must like Jabba since they are guarding the entrance area. When you get to Jabbas front door, the little Robo-Eyeballs pop out the door. You must zap them with lightning to short out the security.
At Jabbas:
Battle some of Jabbas Gamorrean Guards until Jabba opens the door and invites you in.
Cutscene: Talk to Jabba, he gets PO'd and drops you in the Rancor Pit.
While dodging the boulders being hurled by the Rancor, use the force to lift the door and go through. Wait for the Rancor to come after you and drop the door on his head (Luke did it, why not try it yourself). Now flee the area, cut off a Robo-Eyes to open the doors, kill more baddies. Use force lightning to disable the electric field generators in the ceiling.
When you get to the Droid Torturing room, use the force to sizzle the power droids feet a couple times for an achievement. Use the force to lift the power core on the left side of the door, this will disable the force field and you can pass through.
Repeat to enter the room of Hacked Purge Troopers. Kill them off and use the force to open the doors and jump into the tube. Enter the room with the giant crushing roller. Toss a few Jawas under the roller to get an achievement.
Hey Look, your old Pal Proxy is here, but he's in pretty bad shape. Use the force to pick up Proxy and hold him in front of the Big Robo-Eye in the corner. He will trick the scanner and the crushing roller will lift. Now run and jump through the doors and fire. Just before the end of the tunnel there is a decending tube on the left, jump in it.
Cutscene intro to Boba Fett. It seems the easiest way to down Boba is to constantly zap him with Lightning. So keep dodging and zapping till his jetpack goes wacky and sends him smashing to the ground. Then do the Quicktime Kill.
Now you meet up with Obi-Wan in the Space Port, fight him and then do the Quicktime Kill.
Now you get to fight the Ghost of Obi-Wan who is really only effected by Lightning.
The end.
All in All, quite lame compared to the original game.
Two DLC's and both are pretty useless.
