This info was gathered from various places. Here you go. Enjoy
This is all I have been able to find so far.
Finding the Faire
The faire moves back and forth between Mulgore and Elwynn Forest each calendar month. It will begin Aug 1st (tentitive)
Darkmoon Cards
There are four sets of card decks which can be turned in for trinket rewards. To collect a set you must find cards 1-8 for each deck. The cards are BOE blue (rare) drops.

Warlords: Greater Darkmoon card of Heroism - occasionally heals you while you are engaged in melee combat. [Sometimes heals bearer of 120 - 180 damage when attacking an enemy]
Elementals: Greater Darkmoon card of Maelstrom - occasionally impact an enemy you are fighting with for heavy damage. [Chace to strike your melee target with lighting for 200 to 300 Nature damage]
Portals: Greater Darkmoon card of the Twisting Nether - occasionally pull your spirit back into your body after death and restore you. [Gives the wearer a 10% chance of being able to resurrect wiht 20 health and mana]
Beasts: Greater Darkmoon card of the Blue Dragon - estores mana [2% chance on successful spellcast to allow 100% of your Mana regueneration to continue while casting for 15 sec]
Cards and Trinkets
Elementals = Maelstrom
Warlords = Heroism
Beasts = Blue Dragon
Portals = Twisting Nether
Additional Info from Cold Arm
2: When you combine the deck you get a quest item. The quest tells you to take the completed deck to the Darkmoon Faire. I just completed my Elementals Deck.
3: Unless you ARE of the stated professions that can hand in crafted items, you CANNOT hand them in. You will be forced to rely purely on the beast-type vendor trash collecting. Only Engineers can hand in Green Fireworks, that means.
4: The Heroism Card is actually procced when you take damage, like a Truesilver Breastplate. The Maelstrom Card is an on-hit proc, on a melee attack. (Really wanna see that type of thing apply to ranged. Hunter Love FTW!)
5: The ticket gap is rather big, it goes from 50 straight to 1200 (the 2 Epic Necklaces). And, for those wondering and not wanting to do the math: Hand in 60 of the 20-ticket handins you can do, to get exactly 1200 tickets. I can see the high-grade random item ticket purchase being popular for Enchanters, since it seems to be generally green items.
Darkmoon Faire Prize Tickets
There are two epic necklaces, and a handful of lesser rewards that you can earn from the faire by turning in animal parts and some tradeskill goods. These are repeatable quests, but as your faction with Darkmoon Faire increases, you are no longer able to turn in the lesser ones.
There are no turn in quests for enchanting, alchemy, herbalism.
Tickets are not soulbound, so you can trade them, or turn in items on an alt.
