[Resto] Stats for Challenge Mode?

[Nidale]

What would be the best stats for challenge mode for a Resto Shaman.

I currently have a lot of pieces for each slot over 630 ilvl.
For raids, I use Mastery > Haste > Crit = Multristrike > Versatility

I'm wondering what is the best stat weight for 5 mans.
I think Haste-Crit could be good, what do you think would be the best stats?

My tank is a blood DK.

Also, what about trinkets?

The list I have is:
-Everburning Candle (+intel w/ mana on use)
-Auto-repairing Autoclave (+spirit w/ haste proc)
-Blackiron Micro Crucible (+intel w/ multristrike proc)
-Winged Hourglass 3/3 (+intel w/ spirit proc)
-Shards of Nothing (+intel w/ haste on use)

My personal preference would be mastery/crit. Admittedly, I haven't gone for golds yet, but crit and mastery seemed to be most useful, given that surge seemed to be the go to spell.
