As for buy order of honor gear, start with gloves to get glove bonus, then work your way towards 2set and then 4set bonus. If you manage to get the crafted set, you will want jewelry next. Rings, trinkets, amulet, cloak. And from there you just replace your last crafted pieces.
Weapon you have to run a heroic or do LFR.
