Minipickup: Die in a fire (most of you probably can't even see his post, since it was rated down so fast he's at sub-default).
Now on topic... I'd aim for maxing healing while getting a balance of mp5 and spirit. If you spend 100% of your time in the 5SR, 5.5spirit=1mp5. A good goal would be +1600heal and 160mp5 while casting
Consider grabbing tailoring if you haven't. With ZA out the gear isn't quite as overwhelming as it was, but it's still the best available for a long time (plus Blizz has said they want to do the same with with the next expansion, giving tailoring wtfawesome gear). PMC is shoulders, robe, and belt. If you don't go tailoring, the next-best shoulders are Hallowed (until Curator), robes Hallowed (until Bear boss in ZA), and belt is more complicated.
If you've got tons of money, there's a really good belt called Belt of the Long Road. It'll cost you the nether vortexes and crafting fee from an SSC/TK guild though, so I'd guess 1200+ gold. Easier alternatives are the ones from heroic SP, Durnholde, or Primal Mooncloth.
Legs, Whitemend, no question, nothing else comes close until you can kill Kazzak. For the head, the ones from ZA are close, but might be a ways off for you.
The badges gloves, bracers, and cloak are both excellent and fairly easy to get (though the cloak is slightly inferior to the one off Prince).
The neck piece from the Sethekk Halls quest is very good, with the one from Nightbane or ZA being a good upgrade.
Feet, Shattered Halls or heroic Mech, depending on whether you want +heal or regen. There's also Boots of the Long Road, a BoE recipe that makes BoP boots. Gotta have tailoring to get it, and it'll cast a few hundred gold. There's ones from ZA that are about equal, though, so you may just want to hold off.
Trinkets, I'd go with pure +healing ones. The badges one, Lower City revered, and BM ones are all good.
Weapon, go with the one from heroic Slabs or exalted Sha'tar and then replace it with the one from Maiden or Prince in Kara. If you don't want to run dungeons that much, Arcatraz (I think) has a really good one, lots of regen.
Offhand, once again, badges one, either one, depending on whether you'd rather higher higher regen and healing, or higher white stats.
For wand, there's a quest that gives one called Rejuvinating somethingorother until you grab the one from Kara. Sadly, the +dmg badge wand with a Royal Nightseye is pretty good as well due to the severe lack of healing wands.
Gems should all be Royal Nightseye imo, unless you've got a really awesome socket bonus or need to activate a meta gem (which you shouldn't, all the healing helms with meta sockets suck until T5 :P), in which case use the healing/int orange gem.
