I just grinded normals till all 5 had 329. Then I started
With the easy heroics bosses for JPs + Bought shields and belts
For all 5 with their 4k JPs from Wotlk.

Then I started doing SFK and BRC giving my tank
Priority on the chaos orbs. I farmed his 6 just waiting on
Truegold for the belt/shield. Already made the chest.

Also in this time I got dragonmaw revered tank helm + exalted boots.
Almost done with Hyjal for the tank cloak then on to Ramktan for the bracer.

Alchemy trink or Eng Helm is also helpful.

At this point grinding up a leatherworker for epic shaman pieces and finishing up the other 2 sham
Eng Helms / epic bs caster shields.

TLDR - Gear priority = tank then healer. Pug = no
