I run the holy trinity setup of pally/resto shaman/3 elemental shaman but I went with this. As you can see, this leaves 4 unused points which were used as follows: one went totem of wrath, one enhancing totems and one guardian totems with the extra points being put in improved shields.

My totem rotation is fire (totem of wrath, searing totem X 3), water (mana/health, still playing with ratio), air (wrath of air, windfury, grounding X 2) and earth (strength of earth, stoneskin, tremor X2).

With the loss of blessing of salvation, I put blessing of wisdom on my shammies last night for a heroic mana tombs run and other than drinks after deaths/wipes (no addons and still working on threat changes) I ran pretty much non stop and my pally did not need one drink thanks to the new blessing of sanctuary and stacking mana totems. However, it was a little disappointing to have my pally lead the damage chart all the way through (not dps, just overall damage). Guess it really doesn't matter if the job gets done but still...
