Since there are druids out there who are unsure on how to gear up this coming week, I have created several lists for people to shoot for when preparing for Mogu'shan Vaults. I've made a list for those who don't want to touch PvP and only use those items that either drop from dungeons, quests, or crafting; one that includes pvp; and one for BiS, full Valor gear set. The full Valor list is quite extensive and will take several weeks to get (considering you can only earn 1k Valor a week).
Only Dungeon gear
---------------------------------------------------------------------------------------
Dungeon Gear + PvP gear
---------------------------------------------------------------------------------------
BiS Pre-Raid
---------------------------------------------------------------------------------------
Keep in mind that I also factored in Brewfest and Darkmoon Fair into these calcs since they will be available at the start of the raiding season.
The only reason I didn't include Delicate Necklace of the Golden Lotus into the first two lists is due to the time commitment needed to get to Exalted with the Golden Lotus in order to accept the quest that rewards the neck.
As you probably noticed Inscribed Tiger Staff is in all three lists. If you don't have an Inscriptionist to make one, Spear of Xuen, Snowdrift's Bladed Staff, or Amber Spear of Klaxxi'vess will work.
Lastly, and it is something that no one really has noticed, but Meta gems no longer require "x number of y color gems" to activate. Have fun with that.
