most ele shaman go 40/0/21 so you get tons of burst and keep NS for spot healing, for gear you want spell crit, stam, int, spell dmg in that order but most gear you want will have 3 or 4 of those stats. It is ok to down grade armor ranks too so dont be scared to but look to upgrade to mail anyhow. Try to use a 1h weapon so you can use a shield but if you cant find anything better then a staff that works also we are limited on weapons for elemental atm. GL and if you decide to do this have fun it is a great spec for pve and it can become very powerful. The only downfall is your dmg comes from mana but once your crit is high enough things start falling into place and makes your mana last much longer and even when your oom you will learn to find ways to sqeeze out more dmg.
