I see you've chosen not to divulge your alignment. Expect the opponent's campaign to launch attack ads asking what it is you have to hide.
Hmm...you did human for the bonus spells known, so you pass "building a pathfinder sorcerer 101"...
The stats are interesting. Were they rolled? Or did you just want an oddly balanced stat array? If you had a say in the matter, starting cha would have been 20, 22 by level 8, 24 after item....
What is giving +1 initiative? I see the dex and feat, but not sure where the other 1 is from. That 500 gp iuon stone?
Do you get traits for this game, or no?
What sources are allowed? If UM is, have you seen the Eldritch Heritage feat line?
Any particular reason you got a dust mephit?
Have you looked into the new PF metamagic feats? Many of them are very, very good, and I find metamagic works quite well with a spont. caster.
Spells:
0: I'd suggest Ghost Sound.
1: God Spellcraft is often enough so that you shouldn't need Identify in PF. Obscuring Mist is no better from you than it is from a CL 1 wand, I'd drop it. Likewise featherfall is a cheap ring. I suggest Color Spray and/or Ear-Piercing Scream, Anticipate Peril (it's like a cruddier Nerveskitter), and Grease. How do you not have grease?!
2: Alter Self severely sucks now and isn't much better than enlarge/reduce person. Create Pit and its later version can be interesting to consider; some claim since it's an extradimensional space teleporting out of it won't work. Unnatural Lust is pretty weak but great fun at parties. Mirror Image got super buffed in PF, and when combined with high AC and miss chance makes you virtually untouchable (or they close their eyes to swing blindly and effectively turn it into a level 2 10x duration displacement spell) and the rules have explicitly made cleave/great cleave, magic missile, and whirlwind attack all fail to destroy images.
3: All of your choices seem completely fine. Communal Resist Energy is great value and may be worth learning instead of the single target level 2 version. Stinking Cloud is excellent, of course. Ray of Exhaustion is deliciously spammable. Haste is very powerful in a party w/ few casters.
4: Well, you just started out here.
But Ice Storm is very weak, IMO. The damage is terrible, you mostly want it for the diff. terrain. But compare it to
Stone Call, a level 2 spell w/ no SR. That reminds me...you should take Stone Call for a level 2 spell. For your first level 4 spell, I suggest Black Tentacles, Greater Invisibility, Enervation, or Fear.
