A slightly different monk gear question

[crkhobbit]

Having trouble finding suitable items for my three worst slots:
Shoulders
Legs
Feet

I'm lvl 35 and currently using cured silk in these slots (raw silk legs because I apparently forgot to make the cured silk). I've been looking for Wu's, unsuccessfully, which is somewhat irrelevant now because I spent the last plat off of my mule last night. I of course can save up again if those are the pieces I should really get.

What level can I reasonable expect to get Crescent? How hard is it to get, and how rare is it?

Is there something else I should be looking for? I guess I could camp the AC for the legs, but would prefer to get xp.
