FireBall Sorc

Can someone give me a basic stat/skill/item runthrough of a pvp sorc that uses fireball as her main attack?

I want ehr to be versatile versus melee ranged and other elemental.

I was thinking maybe

shako, ber'd cham'd (i will probably be walking as well as teleporting) or um'd.
Perf magi(um) shaft (um) or stealth
Wiz (can i get 15 res and 7% fhr?)
Magefists
Maras
Dual Soj's
<insert boots here>
-15 req/15 res SS

Charms: 5-7 Fire skill, Some FHR, some res and some r/w (again i want to be on foot as well as teleport)

For stats: enough STR, max block, Rest vit, base energy

Skills: Max fireball/mast then Orb with 1 in cold mast after pre-reqs add rest to hydra?

Im not excactly sure, can someone help me out? thanks.
