Choose any regular class you want. They are all good in their own way. The only reason why I choose Soldier is for the full armor use Feats given and the 10 HP per level. I dumb down my constitution and get only 8 HP per level. I usually start my characters out with 18 WIS and 16 CHA. I only have an 8 STR to start with, but I just hang back and throw Grenades. I always choose the single Light Saber route; because, the Feat for single melee weapon gives you a +1 attack and +1 defense each time you choose it.
Yes, it's difficult on Taris, but once you become a Jedi you become very powerful! When you become a Jedi you should throw each stat point you get into WIS since that is your primary stat as a Jedi. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
