Change your cloak to 'of the Sorcerer', and put +5 All Resistances on it.
I'd use 100 HP on chest.
[item]Gold-Flecked Gloves[/item] in stead of [item]Magefist Gloves[/item].
I'd suggest using a belt you can actually use, [item]Enumerated Wrap[/item] of the Sorcerer is a good choice.
[item]Godfrey's Britches[/item] in stead of [item]Darkweave Breeches[/item]. If you're going to stick with your current legs you should put 24 Armor on them in stead of 16.
[item]Spidersilk Boots[/item] in stead of [item]Conspirator's Slippers[/item], and I would definitely take Minor Speed over +7 Stamina.
If you can afford a Facton Change, I'd suggest a 2nd [item]Seal of Argas[/item]. If not, use [item]Garrosh's Pardon[/item].
Using that hit rating wand when you're not planning to hit cap is plain stupid. Either use [item]Firebelcher[/item] in stead, or combine your current wand with [item]Grand Staff of Jordan[/item] (I'd recommend the staff).
