Not a bad start but there are some curious gemming/enchants or lack thereof - there are still a lot of upgrades available to you even if you do not raid. In general you will see the most dps gains by following this general rule

hit (to cap) > Spell Damage > Haste >>Crit

(haste is about twice as good for Ele Shams as crit)

I would recommend using RAWR as the latest version is a pretty good guide (though the earlier builds were frankly terrible) and downloading the latest SEIC from Bink's Blog on EJ if you prefer a spreadsheet.
