Just wanted to throw out a suggestion on the monk.
Watch a kung fu movie or three before making any changes. The monks really need more of that kung-fu flavor. And that means monk weapons that folks will actually use.
Monk weapons should not be inferior to unarmed strike. What they do now is fine for a non-monk, but in the hands of a monk a monk weapon should do their unarmed strike damage plus something extra. (Sort of like the drunken master Prc) Here are some suggestions off the top of my head
nunchaku - +2 to the DC of a stunning fist attack, +1 damage
staff - +1 to AC, +1 damage
kama - +2 to trip
sai - +2 to disarm, +1 damage
singham - +2 damage
I would also add spiked chain to the monks weapon list.
spike chain - reach
of course you should still be able to flurry with any monk weapon.
