Soldier/Guardian?
You really can't go too wrong with that. A lot of feats. Nothing too hard early game for the soldier class and late game assuming you go light side which you already said you can just have party members solve all your problems.
10/16/14/10/12/12 or something like that will work just don't use Vibroblades much and Strength isn't important as long as it's not negative.
