Easy Studs
At the start of Chapter IV, Episode 1, build the first two control panels. After building the control panels, move to the left of the room, and pull the lever. Keep pulling the lever and collecting the Studs. Repeat this as many times as desired.
Use the following trick to get over 50,000 Studs easily. Go to the Podrace, and use one of the speeders from the beginning of Episode II. These are great for hitting the pink crystals because they have better mobility. Use Subulba's Podracer when hitting the little poles. It is easier to hit them with a wide Podracer. You can easily get over 50,000 Studs each time, and it is one of the quickest levels.
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 is a location that gives a lot of Studs. In "Episode VI: Return Of The Jedi" 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.
At the start of Episode IV: Chapter 5 - A New Hope, get to the part where you must build the giant door and break it. Make sure you have the "Character Studs" and "Stud Magnet" cheats enabled. Keep killing the Stormtroopers until you have the desired numbers of Studs, then complete the level. Note: It is also recommended that you enable "Invincibility" so you cannot lose Studs or die.
Bowling
Use The Force to pick up the blue glasses on the floor of the Cantina and stack them up. A bowling ball will appear. You can use Force Throw to it into the stack of blue glasses to get Studs.
