I recently rolled a monk myself after reaching pl100 on other 4 characters ... one thing i hv to say is .. a TR/Bell monk can be a fast & efficient DE farmer (second would be barb but monk hv high mobility with endless resource + huge burst dmg). With that being said, i highly recommend u invest in  good TR/Bell gear 1st (LS Dex Skorn & 3 piece Innas) then use it to farm DE on mp5-7. Reason being with plenty DEs u can start crafting, since BoA craft can provide with u with BiS gears (harder n more xpensive to just buy off AH). Once u are satisfied with ur crafted BoA gears, then u can start upgrading/switching to DW (cookie cutter) build .. which can be very xpensive to gear, just the 2 wpns alone will cost  a big chunk of ur budget.

p/s: btw a TR/Bell monk with good ehp also rawks in PvP .. u can get payback on ur DH/WD frens with Bells lolz
