First, complete Lego Star Wars as well as Lego Star Wars II: The Original Trilogy. Then, start a new game and go back to the first game, which should be completed 100%. Turn the "Old Save" on and the extras that you want on in the new game(This is on "Extras" under the Pause "Menu"). Go back to the 2nd game and the extras are all still with you, even though you have not earned enough money for them in the 2nd game. If you turned on all the stud multipliers in the 1st game, in the 2nd game the Jedi Status stud bar will be very easy, so be prepared for tons of studs.
