After you hit Hellfire, where to next?

Made a post about hitting Hellfire instances for tank gear. Now, I'm looking at the Coilfang Reservoir. First up - The Slave Pens.

Coilfang Reservoir: The Slave Pens
-- Back:
Bogstrok Scale Cloak drops from Rokmar the Crackler.
-- Ranged
Coilfang Needler drops from Rokmar the Crackler.
-- Chest
Unscarred Breastplate drops from Quagmirran.

Coilfang Reservoir: The Underbog
-- Neck:
Talisman of Tenacity dropped by Ghaz'an.
-- Back:
Cloak of Enduring Swiftness dropped by Swamplord Musel'ek.
-- Legs:
Greaves of the Iron Guardian dropped by Swamplord Musel'ek.
-- Shoulder:
Pauldrons of Brute Force dropped by The Black Stalker.
-- Ranged:
Needle Shrike from Hungarfen.
-- 2H Mace:
Hatebringer dropped by Ghaz'an.

So there's at least the first two instances in Coilfang and the first four instances I'm going to gear from in BC for my tanking experience. I'll be looking at the quest rewards from levels 60 - 62 and then posting my goals for gear by 64.
