If you are looking to build a decent Monk, do yourself a favor and have a look at Oriental Adventures.
It has an expanded list of special Monk weapons (finally, the quarterstaff is included), more unarmed feats, martial arts mastery, 3 reasonable Prestige Classes designed for Monks that increases their unarmed attack progression, Monk AC and Speed, Knowledge (Religion) as a class skill, and the opportunity to swap out the stunning attack, deflect arrows and improved trip feats for other feats from a selected list.
The unarmed feats have 3 basic themes or trees you can build (from memory):
1. Striking (increased damage from blows).
2. Stunning Fist dependent feats (with some different saving throws so that you are not always relying on the opponent's Fort save)
3. Grappling.
Between OA and Sword and Fist, you can get some pretty neat combos. One I have been thinking about is Power Attack, Mantis Leap, Power Lunge, and Flying Kick. A possibility of a Jump/Charge attack that would deal around 2d8+(6xSTR bonus) damage [please correct me if I got the multipliers wrong]. Combined with the mastery style that grants +10 on Jump checks, I can see a Monk leaping around the battlefield with Flying Kicks.
