Darkmoon Necklace - Take up skinning and head over to Winterspring *wink*
Thorium Brotherhood - All the quests, then the hand ins (kingsblood, leather or iron), then dark iron residue.
I got my necklace last month, and after not seeing Finkle's Skinner or Zulian Slicer drop in a LOT of runs, I dropped it for my favoured Engineering.
Costs a fortune to level though...Got 40g and no epic mount.
