So, here's what I'm using right now. I've severely overhauled my ui during the past week, but I just can't seem to make the final steps to making it as clean as I want it, as well as fast and efficient. It has changed somewhat, I removed the portraits from my pitbull raidframes, as well as moved ShieldsUp a bit so that it was more in position and not cluttering up my screen, and I've also removed the target's target icon (for now) to save space. I have also deleted the bag menu and the micro menu.
Addon list (my computer doesn't want to take screen shots of non wow stuff for some reason... :[):
What you see
Grid (raid frames in the bottom center)
Pitbull (unit frames to the left and right of my character)
Elkano's Buff Bars (buff list in the top right left)
Recount (damage meter)
Quartz (cast bar)
Totem Timers (4 icon totem bar on the bottom right)
ShieldsUp (Text monitoring water shield and earth shield)
DeadlyBossMods
TitanPanel (The bar along the top of the screen)
Bartender 4 (action bars [will probably change the location/nature of these as well])
Scrolling Combat Text (sct)
SimpleMinimap (customizable minimap)
Minimap Button Frame (top right, click it to see available addons for configuration)
What you don't see
Bagnon (Bag/bank interface)
Bagsort (Makes your bags easier to manage, just type /bagsort or /banksort)
Informant (ilvl of gear, and other things? it's informative

)
PAWN (leet, found this addon here in the shaman class thread, great for any class imo, recommends gear for you)
Beancounter (not sure what it does?)
AtlasLoot
I'll edit my post and throw up some more screen shots because I want more input on how to streamline my performance, but unfortunately wow is being updated right now, so that'll have to wait :[
Let me know if you have any suggestions for improvement!!!#!%@$!%@$% Keep in mind that I AM a healer, if you couldn't tell from my gear/cast bar/other stuff, so if you could somehow tailor it to suit my needs that would be great, if not, your advice is still much appreciated
