I'll take on Karf first since he has been fogotten:
Well, as you said you have no intention to bubble spam, but I really don't think that should keep you away from getting tier hands and pants, all you loose is a minor amount of sp and then swap some crit for the sake of spirit (both stats are arguably useless), but it's your choice and your gear lineup does look really neat. But, I see a lot on inconsistancy in your gemming; your chest and pants have the same socket layout and bonus, yet you gem them differently, same goes for your hands and feet, and you have chosen to actaive a 7sp blue socket with a purple gem in your belt, but not your 9sp blue socket in your head.
Varaben: you logged out in your shadow spec and gear, but I can raid that if you don' mind ^^
Well, short version is to get 4p tier10, other than that please go over your gems, those sp/int gems are just not right (I'm of course only thinking of those you dropped in your hit gear, since you might be using some of the none-hit oieces in your healing gear) and your gemming in your legs should be swapped to sp/haste + sp/spi so that you get the socket bonus. Your head and shoulder enchants should also be replaced to the dp/crit versions and it's a really good idea to have runspeed on your feet (that goes for shadow as well for healing). Please get 10 stats on your chest.
Here is my armory:

I do as most Disc priestess and favor spellpower the highest, other than that I have been picking up as many haste/regen pieces as possible due to 2 things: I find crit rather useless and random (and it's way better spend on the dpeses imo) and I like to be able to dish out fast heals whenever I actually have to go there; I find it helps counter that disc heals is'nt scaling as well as others healer's healing.
