Why 2x perception? If you have a good reason, then go for it. If not, then based on your current training, I recommend that you rotate through a weighted training regimen in the following skills:

Harness power x1.5
Magic item use x1
Arcane symbols x1
Elemental mana control x1
Spirit mana control x1
Either spiritual summoning or elemental lore x4
Either demon lore or necromancy lore x1
Combat maneuvers x1

Pick either elemental or spirit summoning lore and train in it until you are fully singled. Then you can decide whether to double in that lore. The primary benefit to elemental lore is DC. The primary benefit, IMHO, to spirit summoning lore is web bolt.

No matter which Sorcerer lore you choose, you might as well get 20 more ranks in necromancy to reach the capped like-level MAL threshold and to improve your use of FLD.

Also get at least two ranks of multi opponent combat.
