The Wildheart Raiment Set pieces drop from Stratholme, Scholomance, and Blackrock Spire.

Head: Drops off of Darkmaster Gandling in Scholomance
Shoulders: Drops off of Gizrul the Slavener in BRS (Blackrock Spire)
Chest: Drops off of General Drakkisath in BRS
Wrists: Drops off of various mobs in Stratholme and Scholomance
Hands: Drops off of The Unforgiven in Stratholme
Waist: Drops off of various mobs in BRS and Scholomance
Legs: Drops off of Baron Rivendare in Stratholme (Undead side)
Feet: Drops off of Mother Smolderweb in BRS

Also, the Belt, Bracers, and Gloves are Bind on Equip, whereas everything else is Bind on Pickup.
I hope this helps.

Looking over the four non-raid sets, I think it works as follows... Wildheart is good for healing/long duration caster DPS, Feralheart is good for more high caster DPS (less duration, but still) and bursts of feral work, while the epic PVP set is great for feral of all kinds and for high burst damage/PVP style casting... superior PVP set is basicaly a less powerful verson of the epic set (obviously).

This is the Druid Dungeon 1 set, collected in 60th instances pre-tbc. They are used to upgrade to Dungeon 2, and the other sets are:

https://vanillawowdb.com/?itemset=181 Magister's Regalia - Mage (Cloth)
https://vanillawowdb.com/?itemset=182 Vestments of the Devout - Priest (Cloth)
https://vanillawowdb.com/?itemset=183 Dreadmist Raiment - Warlock (Cloth)
https://vanillawowdb.com/?itemset=184 Shadowcraft Armor - Rogue (Leather)
https://vanillawowdb.com/?itemset=185 Wildheart Raiment - Druid (Leather)
https://vanillawowdb.com/?itemset=186 Beaststalker Armor - Hunter (Mail)
https://vanillawowdb.com/?itemset=187 The Elements - Shaman (Mail)
https://vanillawowdb.com/?itemset=188 Lightforge Armor - Paladin (Plate)
https://vanillawowdb.com/?itemset=189 Battlegear of Valor - Warrior (Plate)

REMEMBER: These don't have class restrictions. You can use any that you can, but the stats are tuned to the particular classes. You also require your class's set before upgrading to Dungeon 2.

Does anyone know of a weapon that matches well?

As of patch 4.0.3a, it has seemed like they removed the Dungeon One sets from the game. Reply if i am incorrect, but i have done the old dungeons, and no D1 is dropping where it should be.

There was a http://us.battle.net/wow/en/forum/topic/2973026165?page=27#524 blue post from Kaivax the other day regarding dungeon sets and the like:<div class=""quote"">We would like to offer some alternative ways to get favorite items that are no longer available, such as perhaps the dungeon tier sets or the DK start gear. This is something we will expand over time not every favorite item will be immediately available at launch. But we'll keep a list of items that get requested by the players and work to get them in someday.</div>Otherwise there's an alternative of getting the BC dungeon set look-alike https://vanillawowdb.com/?compare?items=27409:24455:24452:24391:27417 https://vanillawowdb.com/?compare?items=27409:24455:24452:24391:27417
