New sorcerer build

[Bigdaddyjug]

This is for a PFS character, so it's a 20-pt buy as well as some other restrictions.

Here's what I'm thinking:

Tiefling Wildblooded (Sage) Sorcerer
Str: 10
Dex: 16
Con: 12
Int: 20
Wis: 10
Cha: 5
Saves: Fort 1, Reflex 3, Will 3
HP: 7
Init: +3
Traits: ***
Feats: Eschew Materials, ***
Gear: Light Crossbow, Silken Ceremonial Armor, Everburning Torch

Cantrips (at will): Detect Magic, Read Magic, Light, Daze
Level 1 Spells (5/day): Mage Armor, ***

Special Abilities: Arcane Bolt (8/day)

So, the things I'm having trouble deciding on are traits, a level 1 feat, and my 2nd level 1 spell.

Traits: I would really like to pick traits that give me additional class skills, particularly knowledge skills since I will have a high Int modifier. However, PFS restricts you to only 1 trait from each category of traits, and most of the traits that add knowledge skills are "magic traits".

Feat: I feel like I should take Spell Focus in some school of magic, but I don't know which. Are there any other feats worth looking into at level 1?

Spells: Mage Armor is a given since I'm going to be a sitting duck with only 14 AC and 8 HP. My 2nd level 1 spell is a different story. I feel like I should pick an evocation spell like magic missile or burning hands, but Arcane Bolt has 8 uses per day and I'll be fairly handy with the light crossbow I carry, so I'm not sure it's necessary. What spell I take will go a long way towards affecting what feat I take at level 1.

Any other advice is greatly appreciated.

Color Spray is always a solid option at 1st level, and you can trade it out at higher levels.

Yes, I was thinking either color spray or grease, or maybe dropping mage armor and picking up both of them. Then I could take Spell Focus in either Conjuration or Illusion.

Is there any way other than the Etymologist trait to get Linguistics as a class skill? I figure with a +5 Int modifier, I may as well put ranks in it and know as many languages as I possibly can.

Also, still not sure what to take for traits. Selecting traits for a physical damage dealer is fairly easy. But for a character that's going to be 1 caster class the whole way through, it's much more difficult. Should I worry about initiative on a sorcerer?

Also, if there's another bloodline that works better than sage, I have no problem being a musetouched aasimar (+2 Dex, +2 Cha) and rearranging my stats to suit.
