I only use one resource for quests (well, ok, i'll head to eq2players forums if I absolutely have to). My main source of info is Ogaming. If it's not on there, it's more often than not anywhere. I've really only seen a few incorrect pieces of info on there, but people usually do a pretty good job of submitting corrections to the site.
Simply put, Ogaming.com is the best fer EQ2 quests.
