Seconding the tradeskill achievements. Tradeskills are one of my favorite parts of the game. Maybe it could be broken down like "First to achieve a skill of 50 in Baking" ... "First to achieve a skill of 100 in Baking" ... etc. etc.
I also think it would be fun to have "First to Forage [item name here]" for those zone-specific items that require a higher skill in forage. One example might be "First to Forage a Morning Dew" ... oh, and also, "First to achieve a skill of 200 in Forage"
Here is the Wiki link for Foraging which lists all of the zone specific items:
