The aurulite armor/weapons/jewelry you can get in Killaloe is really great for leveling. I highly recommend it, plus the experience gained from the quests (and the kills required by the quests) is excellent.
I used my thidranki aurulite armor in task dungeons well into my 30's. The armor finally turned grey so I wasn't getting good AF from it, but all my important attributes were still overcapped. I used the trainer supplied chest/weapons as well, but they stop after level 30.
Beyond that, you're going to have to quest for it or buy stuff from peoples merchants in housing. This is what I ended up doing after 35.
