Getting your first Earth Keeper set
Earth Keeper equipment is "upgraded" piece by piece from quests found at the Temple of Earth in Deepholm (New Quest Zone PVE)

For each item, you are required to hand in the relative slot's Lavaroaring, Tidewalker, and Thunderfury equivalent - along with 100 Energy Mounds and 30 Fallen Sky Stones, with a cost of 800 MG: So for instance, the materials required for Earth Keeper Paladin Shoulderguards are Lavaroaring, Tidewalker and Thunderfury Paladin Shoulderguards, 100 Energy Mounds, 30 Fallen Sky Stones and 800MG.

Upgrading Earth Keeper
Earth Keeper can be upgraded through farming, just like most other items on Eternion. For this, you are required to bring special items to the Earth Keeper in the Temple of Earth. The required items are found from mobs and bosses in the Hot Dungeons, and from voting.

Earth Keeper I+ vs Earth Keeper I+ (Hero)
While at first this debate may seem a no-brainer due to the Heroic version's increased stats, it is worth noting that the difference is not quite so simple. For a start, the (Hero) set is only accessible by VIPs, and requires Fine Iron instead of regular Iron for upgrading - Fine Iron can only be obtained through voting and requires a large number of vote points per item, essentially setting a time restraint on your farming efforts.
