Drop whichever totems your group leader thinks will help the best, Stormstrike whenever it is off cooldown, and earth shock whenever you get the proc for lowered mana cost and you are ok on threat.
Very close.
Stormstrike every time its off cooldown, and always make sure you include Flame Shock in your rotations. Flame Shock does more DPS than either of your other two Shocks even with Earth Shock getting the 20% bonus from Stormstrike. The exceptions to this rule would be if the mob is going to die before the DoT has a chance to run its full duration or you're ready to Shock again and you already have a Flame Shock DoT running.
So, similiarly to what Bigdaddyjug said, lay the totems that will best benefit the party as a whole (
not your own personal DPS), keep Stormstrike on cooldown, and rotate Flame Shock/Earth Shock as needed.
