Ravenwing Pauldrons: Dropped by Lieutenant Drake in Old Hillsbrad Foothills
Flamestrider Robes: Dropped by Pyromancer Loregrain in Blackrock Depths
Manimal's Cinch: Quest reward in Shadowmoon Valley
Devilsaur Gauntlets: Crafted by leatherworkers
Righteous Bracers: Green BOE. Or any small bracer that doesn't show under the Devilsaur Gauntlets.
Jinxed Hoodoo Kilt: Drops in Zul'Farrak. It has the same model as the bottom part of the Flamestrider Robes, so it doesn't show.
Staff of Earned Tranquility: Low level Worgen only quest reward. There are plenty of other staves that would work with this for a non-Worgen.
