IMO Enhancement is the way to level, this will mean your primary damage will be melee with the occasional shock spell.
Your stat priority should be Str (Attack Power), Agi (Crit), Stam (Health), Int (Mana). At higher levels you will be able to get gear with straight crit and Mp5 but for now just go with the stats I mentioned in that order.
For build advice check the thread in my sig.
