Elemental DamageFollow

I a lowbie 63 with 302 sp unbuffed and about 440-ish buffed, I was wondering whats a good rotation to maximize my damage output.
(Of course I'm elemental speccd)
-Best desicion since being a shammy-
I normally do roughly about 475-600 dps. (depends on the situation)
Or is my damage good for my level

Here is my Armory: http://www.wowarmory.com/character-sheet.xml?r=Arthas&n=Taeger

All tips appreciated.
