Well, when I met with the DM to finalize everything, for stats he decided to go with 4d6, drop lowest, and reroll if its 10 or less, so I ended up with the following stats, after racials:
STR 11
DEX 19 (+1 at 4, 8, 12)
CON 12
INT 16 (+1 at 16, 20)
WIS 12
CHA 9
I've decided to focus on using Arcane Pool for enhancing my weapon and recalling spells, so with that in mind, I changed my feats and arcana accordingly:
1 Weapon Finesse
3 Dervish Dance
5 Arcane Strike
5b Weapon Focus (Scimitar)
7 Intensified Spell
9 Lunge
11 Extra Arcane Pool
11b Empower Spell
13 Quicken Spell
15 Spell Perfection (Shocking Grasp)
17 Spell Penetration
17b Combat Reflexes
19 Greater Spell Penetration
3 Familiar 
6 Lingering Pain
9 Spell Blending (Touch of Idiocy, Resist Energy)
12 Maximized Magic
15 Quickened Magic
18 Ghost Blade
There's probably better feats than spell penetration that late, but I figured that even before that point, SR would be somewhat common, so overcoming it would be nice. 
As for spells, I was going to take the common buffs, touch attacks, utilities, with Bladed Dash and Force Hook Charge for mobility. When dealing with electrical immune opponents, I'd mostly focus on using debilitating touch attacks, and generally helping out the other party members with spells. 
If I start taking 1/4 Arcane Pool at 8 for my favored class bonus instead of health, by 11th level I'd have 13 Arcane Pool (5 from stats, 5 from levels, 2 from feats, 1 from favored class), which gives me plenty for enhancing my weapons and recalling Intensified Empowered Shocking Grasps. 
I think I'm generally pretty happy with my new build, but I just wanted to run in past the braintrust one more time. Thanks again for the feedback and help, everyone. 
EDIT: Oh, equipment question. Besides Pearls of Powers, and stat/armor/save boosters, what should I look at picking up? I was thinking of spell storing on my weapon and boots of speed.
