The quests seem to cover all of the secondary skills, but be aware that for the Archaeology quest you'll be asked to "donate" some of your fragments. They really mean that too, the quest will literally remove some of your existing fragments from an artifact in progress. In my case it was a Fossil artifact, so I wasn't too heartbroken about it.
I also found these two quests for my Leatherworking/Skinning skills. No actual skinning was involved, just "skinning" quest objects on the ground. The Leatherworking quest had me making some items which required crafting materials from a trade vendor. The Faire grounds have a portal to Elwynn Forest (and Durotar I assume) so you can easily get back to a major city. For Alliance you can use the Trade vendor by the wagon in Goldshire to purchase your items.
I found these quests to be entertaining because I was using my tradeskills to complete them. For the Fishing quest I actually had to fish, not just pick up stolen barrels of someone else's fish. The Cooking quest required me to get some actual flour from the trade vendor and use it on the froggy bits from the quest NPC. Overall I felt these quests were better designed than most of the Cooking/Fishing quests we got for Cataclysm. The only thing I might have done differently would be possibly send you a little further out around the DMF island to complete the tasks. But I was pleased to see that many of these quests incorporated crafting-like actions in them.
Sadly, these quests are not dailies. You can only do them once, unlike the carnival game quests. I posted a suggestion on the forums to turn these into dailies, but I don't know if anything will come of that. It's possible that when the DMF is activated each month that the quests will unlock again, but for now that's unknown.
And as I mentioned at the beginning of the post - no recipes in sight. I looked all over and couldn't find any vendor selling recipes. I found vendors selling food, drink, pets, transmog gear and heirlooms. But I could not find any recipes at all. I would like to say that maybe they'll be added in another build, but the Faire looks pretty complete at it stands. So I'm not sure what to think of the missing recipes. I posted on the PTR forums about it, perhaps that will help in some way. I'm disappointed though, I was looking forward to see what they had in mind for Darkmoon recipes. I thought maybe some additional transmog gear or something.
