Story Mode
True Jedi: 70,000. This can be a little tricky as there does not seem to be a lot of things to shoot. However, shooting Droid Tri-fighters and Vulture Droids gives you studs as well. You will likely need to do this in order to get True Jedi. Also, each MK gives you a blue stud so that helps a lot too.
Vehicle: Jedi Starfighter (Yellow) (NEW) AND unlock Jedi Starfighter (Red) (NEW)
Available for Purchase: Clone Arc fighter, Droid Tri-fighter, Vulture Droid
Enemies: Droid Tri-fighter, Vulture Droid
I believe this is the only level where you are able to collect all of the Minikits and the Power Brick in Story Mode. This is so, since you do not get to roam free in this level; your path is set, but you can move around to a certain extent. However, be careful not to run into the large ships, as you can blow up, and then you will go back to your last checkpoint. The controls are also different in this level. Sliding up will cause you to go down, and vice versa.
The first area where you have to do something, you will see 5 large circles in front of you on a ship. Blast these, which will clear a path for you to fly through. A little ways on there will be a structure sticking straight up from a ship with red circles to shoot. Shoot these to clear the path again. Shortly after will be an obvious door. Shoot the 2 red circles to open the door, which you will fly through. In the last stretch is Grievous's ship, the Invisible Hand. There will be two red circles on each side of the large force field to shoot to disable it before flying in and completing the level.

Total Studs: N/A (you can get studs from enemies, and the amount of enemies do not seem consistent)
***Note: Do this easily in Story Mode!!! Also, descriptions are a little vague but most of these are hard to miss. I already grabbed MK #10 in Story Mode.***
