I used my healer, with lightning spec. Basically just wheel around him, keeping a shield up as much as possible, interrupt his force storms and other powerful attacks and avoid his death fields with Force speed (and any other area effects).
Make sure your healer is geared up so he works well, he should basically keep your health full at all times. And a combination of avoiding and interrupting attacks will ensure your health stays high. Just keep wittling him down and eventually he'll die.
And it helps if your lvl 50 - if your not then I suggest you lvl first.
P.S. Concerning boss fights, healer is always a good pick for a sorc.
You cann't interrupt his force storms, his attacks are mostly aoe, just run away from it, save the interruption for the heals.
