well the way i see it isa cold lightning sorc... but i would recommend more warmth do u dont have to scavange around for mana pots all the time lol but anyway i have some sugesstions for items on that kind of a sorc....
Oculus+Lidless wall
Shako
Perfect Skin of Vipermagi(+35 all resistances) (unless your a mf sorc then u should use Skullders Ire)
2 soj as rings
Tal Rasha's amulet (if your a mf sorc.. use the rare duped ammy Viper torc 48 or 49%mf WOW)
Either Waterwalk boots or Silkweave boots
Since your a cold sorc with this combo you should use Frostburn Gauntlets....(considering the fact in the expainsion pack they didnt make any good unique gloves lol)
then get a bunch of charms most likely 5%resistances small charms and you should be set if i forget anything or there are any other suggestions be sure to reply - peace
