I think the player should be given the option of choosing what species they want their Jedi to be (Rodian, Twi'lek, Ewok [lol], human, etc.)
My five planets would be: Dantooine, Coruscant, Alderaan, Dathomir, and either Naboo or Deralia.
As for robes, maybe there could be some way to combine the robes of I and II, so the player may have the choice to remove the cloak and fight in the looser robes when necessary (like fighting a big boss, Sith Lord, etc.).
And maybe, for once, have a Sith Lord has is not scared in any way (Sion, Palpatine, Malak, Vader, c'mon, it's getting old).
