I have described the different quests, as best as I could, on the reward's page.
Quests seem to generate based on raid ID, not server. Unfortunately this means you might get screwed and get a quest for one of the much later (or harder bosses) while another group could get a real easy one.In time they'll all be easy.
Just as a side note, as long as you pull BQL before the timer expires, you can still get credit. We wiped once on Princes (lol fail) and then stood around for a while switching people in/out for BQL, and pulled her with 1-2 minutes left on the timer. We 1 shot her and still got credit for saving the NPC.
