First post should be updated to reflect all known info. Feel free to fill in the bits and pieces we're still missing, thanks so much to everyone.
And yah, I think these quests were, as Loretta mentions, meant to be done as we're leveling. It'll be nice for lvling folks to have more to do, and get rewards for things they're already doing. But getting them all at lvl 49, for recipes we've already mastered, is a bit annoying. On the other hand, bear statue! I expect to see you all proudly displaying them... RAWR!
