Area Bosses - Which is which and how to find them

I was kind of hoping posting droplists would be postponed for a while because nothing is more annoying than having to sit around for an hour with 20 other people waiting for a quest boss to spawn and hoping you're the one who makes the kill. It's going to happen for the first few weeks already (Mano...) but knowing which ones drop the good things they'll be there all of the time making it hard for those who just want to complete the quest to get it done.

Eh, if it's not here it's somewhere else. Sucks though.
