There are several ways to get studs by destroying chairs, trash cans, etc. There are two fan covers on the ground outside the cantina that give lots of studs. Inside the cantina there is a location that gives a lot of studs. In "Episode VI: Return Of The Jedi" there is a table in the middle of the room with blue chairs. Use The Force on these chairs several times. Some studs should appear each time this is done.

keep going to the very first level (negotiations) and in the room you start off in you can make all the chairs dance to get studs, then you can move each chair to get more, there are studs lying about the room, and canisters in the corners of the room. Then as you go into the hallway, you can go into the different rooms, and destroy more canisters and more studs are everywhere in this level, well worth it if you are desperate for money.

in the cantina force all the cups/stools/lights to get some studs, then destroy all the chairs/red cups/bins and bowl, also outside there are barrels, bins, fan grates on the ground, also in each movie room there are certain things e.g. In episode I there is a picture of R2-D2 on the wall, finish building it to get more studs, or build the snowman in episode V for example, and there are more chairs, red cups, lights, bins, barrels etc. in each room, and they reset after you do a mission, so you can continuesly get easy money without losing any if you die. Also useful if you are desperate for money, but dont want to do a mission.
