Here is my list and reasons. . .
(Chest) Wave of Life- this will remain on you for almost forever.
(Legs) Ruined Scales of Antiquity -same as chest, you will need T6 or better.
(Waist) Get the Isle belt last with your badges.
(Shield) Chess, Mags or ZA...keep the blue til then.
These depend on drops, rate you collect badges or guild progression in Kara +
(Neck) Either wait for Banes or work the Isle rep for it's equal.
(Back) Opera or Prince, the Shatt vendor is ok but your badges are needed elsewhere first.
(Waist) Moroes first, once geared out completely then the Isle belt, only +20 heal and a few stats better then the Moroes one.
(MH) Maiden, then wait for a better replacement from ZA, SSC or BT. The badge one lacks mp5.
(Trinket) Several options most depending on drops via attendance and rep, 1st prority is your Alchemy trinkets asap. Lower City, Opera and Prince can be done as you do it.
(Totem) Wait on Maidens, do not waste the badges.
While you geared for +heal you seriously lack mp5. A T6 Shaman will have around 2100-2300 healing and 150-200 mp5 unbuffed (depending on Shadow Priest and situation). I am healing Kara, Mags, Gruul and ZA with 1900+ healing and 147 mp5 unbuffed with ease. http://www.wowarmory.com/character-sheet.xml?r=Hydraxis&n=Bly

We all have our reasons and styles which depend on guilds, strats and situations, but I pass this info to you based on gold spent and 6 months farming Kara with short stints of Gruul, Mag and ZA in between. I changed my legs out 5 times which include gems and enchants before getting the Antiquity, all was minor upgrades each time except for the gold I wasted.
If you are a 3rd healer working with experianced and geared healers I suggest waiting for your drops.
