This is a list of cheats I found and there are more I will post when I find them. Just like all other cheats you must enter these in the Rouge Shadow under Extras.
Entering any of these cheats will give u someone who isn't the apprentice to play with, but this will also remove the cutscenes.
god mode-cortosis
This makes you immune to any attacks in any outfit or as anyone, no real consequence for using.
max levels- countdooku
new outfit for apprentice- dantooine
If you want to find some yourself, then collect all the jedi holograms and look at the concept art, some of them have the cheats in the lower right hand corner. These are the few I found and i'm not done with the game yet so i'll post more later on. I have missed some so i'll go back through again and see if I can find them all.
Easy Force Points
Reach a checkpoint that is just before a large group of enemies. Intentionally die during the battle. Every time you respawn at the checkpoint, your Force Point total will remain intact. Repeat the battle to build your Force Points.
Extra Costume
In the rouge shadow, Head to extras and enter the cheat codes menu. Here you will be able to enter the cheat code WOOKIEE and unlock a costume other than the training gear you start off with.
Hint: you can only do this when you play as the apprentice, not as Vader.
Force Lightning
You recieve this extremely helpful force power in the second apprentice mission. This power is majorly effective against most races in the game. Buy upgrades for this force power asap. Especially when you can link your attacks to numerous enemies.
Jedi robe
Successfully complete the game with the Jedi ending to unlock the Jedi robe.

These should be the last cheats you'll need.
