If what I've heard about the 2 specs thing comes to pass, I'll go for something along the lines of the following on most of my shammies, 1 will be PvP/Heal, others PVE/Heal:

PVE: http://www.worldofwarcraft.com/info/...000000000#none

PVP: http://www.worldofwarcraft.com/info/...000000000#none

Heal: http://www.worldofwarcraft.com/info/...000000000#none
(No expert on Resto Shammies though, but this could work in an Mbox group)
