True Jedi Story - 30 000. Most importantly, try not to get killed too often. Take your time and don't be disturbed with the fact that the Emperor is waiting for you to come and fight. Look around.
True Jedi Freeplay - 40 000. It's a lot easier than the Story Mode, mostly due to some cool stud-rich bonus areas.
Power Brick. Use the Force on 8 squares on the back wall near where you fought the Emperor for the first time.
Use the Force to build a platform near the first battle area.
Go rightwards from the starting location and blow up a shiny metal object with a detonator. Build a grapple point and use it.
Right where you fight the Emperor for the second time use the Force on 10 glowing panels on the back wall.
Below the second battle area use the Dark Side on the air vent and build a platform of what's left of it. Now destroy the parts to the right and build a bounty hunter panel. Use it and you'll be able to hover to the minikit as R2.
Go through the door near #4 and light up all 12 panels on the floor by quickly walking over them.
Near the elevators by the center of the level use the detonator to blow up a metal fragment of the wall.
Use the bounty hunter panel in the center of the level, and build a 3PO panel of the loose bricks that came out. Use it and you'll see the next minikit.
Below the third battle area use the tunnel and push down the crate, then shoot its remains. You'll access a hidden room. Place the three armchairs on top of each other and use the tunnel.
In the same area as #8, use the Dark Side on the fan at the back, then use the detonator on its cover.
In the same room as #8 and #9, build a panel for 3PO on the left and use it. Now use the detonator on the metal piece of equipment nearby and grapple up. Use the lever and build a crate. Push it to a green circle on the floor. Destroy the two armchairs nearby and fix a turnstile of their remains. Use it to rotate the box 90 degrees. Push it towards the station to the right. An elevator will turn on - it'll take you to the last minikit.
