This you will need a second controller and another profile (doesn't have to be an XBL profile).
Replay all the levels. I would pick the following Characters to get the other achievements at the same time
The levels you were Jedi on. I would pick Ahsoka as your main character to get the "Girl Power" Achievement and Anakin as your other character to get the "Dynamic Duo" Achievement.
On the Clone ones I would pick Cade Bane as your main character (and whoever as your second) to get the "Nobody Messes with...".
When you start the level drop out your second controller. When the level is almost done hit START on the second controller to jump back in.
