Belt: Anetheron's Noose, followed closely by Screaming Terrors or Belt of Blasting.
Boots: Frozen Shadoweave, no question. Best boots until at least Sunwell.
Cape: Nethervoid, no question.
Bracers: Cuffs of Devastation.
And legs: Absolution legs are crap. Channeled Elementals are far and away better, with Devastation coming up close behind.
Unless of course you meant looks (since you didn't ask about non-visible items), in which case it's probably Belt of Blasting and Shadow-Cloak of Dalaran (the others don't really matter because you can't see them) or something similar. I could probably find even better matches, but I'm too lazy to look into non-dpscaster non-highlvl items :P
