@ Tagan: Something you should consider, and by 'consider', I mean 'get at all costs, including bribing the DM', is the Talashatora feat from Secrets of Sarlona (an Ebberon book). It lets you count Psychic Warrior levels and Monk levels for unarmed damage, AC bonus, and Flurry of Blows. At level 6, that's +1 AC, damage boost from d6 to d8, and reducing the Flurry penalty from -2 to -1. It'll cost 2 feat slots though (Monastic Training - Psychic Warrior and Talashatora) - you would probably want to get rid of either Combat Expertise+Whirlwind Attack or Mobility+Spring Attack - my preference being the latter, because Whirlwind Attack can get quite ugly once you fire off Expansion and become Huge with delicious 15ft reach*, and because Spring Attack deprives you of Flurry, your second-best Monk feature.
*Will require Practiced Manifester, naturally).
