there's two items in ZF which are awsome for DW. aside from that you'll have to go with random AH greens I can't remember any quests...
from ZF i used
Ripsaw - Item - World of Warcraft and
The Hand of Antu'sul - Item - World of Warcraft till level 50 ish.
@ 50ish go to Sunken temple and grab
Tooth of Eranikus - Item - World of Warcraft
