Easy studs
Play Chapter 1 of Episode IV: A New Hope. Destroy all of the little panels that a Force user can open. You can also go through the Bounty Hunter or Stormtrooper doors and use the Force on all of the little panels on the wall. Another way is to go through the door that can only be opened with a Sith (for example, as Darth Vader). Then, use the 2x Score Multiplier to your advantage.

Unlimited Lego Studs
A way to get unlimited Studs is by going to Free Play mode on CoOp, on the 1st level, getting a Sith, then by going out of the first door. Then, walk towards that open door to the right, then it will turn into a black door. Then, get your Sith character to use the Force on the black door, and go into that Double Score Zone. Then, start killing the other character and grabbing the Studs he drops out at double value. Keep doing this to pretty much get unlimited Studs.
