ZulGurub: As we reminded you earlier, this section is for Dragonica Gold fans that do not have the Burning Crusades expansion pack, and cannot progress past level 60.

ZulGurub (ZG) is probably the first real raid encounter you experience (meaning you need a coordinated and routine-trained group to beat the content).

The challenge at this point is not as much your equipment but the raid know-how of your guild. A decent set of equipment centered on tier 0 armor should do the job for the first encounters in here.

While clearing the first few mobs a couple of times you are likely to come across quest components for epic gear that provides the necessary stat increase to deal with the more difficult mobs.

Ruins of AhnQiraj: Nature based attacks are most common so appropriate resistance gear would help even though it is not as important as fire resistance in Molten Core. You need not be decked out in epics, but it is a good idea to have upgraded some of your group instance equipment with at least ZulGurrub armor.

If you got Molten Core on farm status, the 20 man AQ instance probably will not pose a real challenge. Equipment wise you can stick with what you got during your natural progression before and in this zone.
