People are going to bash you for it but I run Healbot with Fluidbars running.If you setup Healbot right you will love it. Next grab decursive very important for a shammy we can get rid of pretty much everything but magic. I run totem caddy, its an old version but it still works, I like being able to cycle my totems and have BL right there without putting it all over my bars. I run elkanos buff bars, I like the way it organizes it. I also like some form of pulse mod, which I place center of screen to notify me of CD's an what not. Omni CC works okay. Healbot also notifies you when your shield, or weapon embuement is going to fail by changing your character pane. I can apply both by clicking on my name. I prefer to scroll to reapply WS.
I have my heals setup for a 3 button mouse. lhw, riptide on the side, chain heal is the middle button. With the scroll wheel down to reapply water shield(Cntrl for lightining shield), and scroll wheel up for NS. I have healing wave bound to F, so i can throw a quick NS HW to save someone. Below is what I have setup, healbot is the thing above my bars it leaves my screen mostly open so I can see everything.
