Just wanted to throw out a couple suggestions. With the overhaul to Monks, it appears unarmed was the intentional route for them to go. I love the idea, but a few minor tweaks would help them tremendously.
1st) Empty body - gives 50% conceal, 2 times a day for number of rounds = to class level.
Proposal to change this to give permanent 50% conceal if you have at least 30 levels of monk or give it a visual affect and give it a number of uses based on half your monk levels. Remove the concealment from the monk necklace set and replace it with something else, Possibly a damage shield of some sorts.
2nd) A new feat for monks or possibly changing quivering palm. Here is a feat from the new Kingmaker - Pathfinder game that I think would work great for monks, replacing quivering palm, but put it on a timer instead of 1 use per day.
:Great Vital Strike"
You can make a single attack that deals incredible damage.
Benefit: As a standard action, you can make one attack at your highest base attack bonus that deals additional damage. Roll the weapon's damage dice for the attack four times and add the results together before adding bonuses from Strength, weapon abilities (such as flaming), precision based damage, and other damage bonuses. These extra weapon damage dice are not multiplied on a critical hit, but are added to the total.
Just some thoughts,
