Fungus Covered Scale Tunic is my favorite twink armor for monk, although the -Agi bites, with newer gear, that can be made up for, and +15 worn regen is amazing at lower levels, add in some regen and skinspike potions and a descent weapons, and your set as long as you keep your wt reasonable.
Knotted Knuckles Adamantite Club Khashek's Katar Zekha's Katar There a few others, such as Horns of Frenzy, and Gold Inlaid Ulak that are good too, but the Knotted are better than those, and the two Katars are easier to get.
Fish Bone darts, both types are an excellent ranged weapon, with low delay, low wt, and exceptional range. Not too difficult to make once you get your fishing and fletching skills up.
Before defiant, I stuck with the stuff listed above + Wu's for low wt armor, as the FCST and weapons, especially store-bought ranged weapons really get you to the lower level wt limits fast. But with regen, good weapons and keeping your wt down and Agi up so you don't loose avoidance AC, you don't really need anything else till the 40s or maybe higher.
EDIT: Fixed link typo, and mentioned the fish bone darts.
