Hi Sam.

Protection From Evil
--Slight bonuses against evil creatures, protects from evil mind control.

Grease
--Good in-combat use, good out-of-combat utility. Very useful overall, if the situation calls for it.

Mount
--Long term summoning spell; can be used for riding, trap detection, an extra creature in combat, and so on.

Charm Person
--Makes low-willpower enemies into friends. Will not attack their other friends, but will assist you in other ways.

(Tenser's) Floating Disk
--So useful it has its own handbook. Even if you're not abusing it, it's still useful.

Magic Missile
--It has good range, it can target anybody without total cover/concealment, it can't miss if it targets them, it affects incorporeal targets, it bypasses most forms of DR, and it gets better as you level up.

Color Spray
--This is widely known as a wonderful Save-Or-Lose spell at the lower levels, although it becomes less useful past 5th level or so.

Disguise Self
--It's decent if you're not good at making disguises; it's wonderful if you're already really good at it, because it can stack with a mundane disguise for a huge total. Lots of out-of-combat utility, but no real combat use (unless you're incredibly creative).

Silent Image
--Pretty solid low-level Illusion spell. Not as useful if you need sound as well, though.

Ray of Enfeeblement
--Decent at low levels, the main benefit from this spell is later on, when you can apply metamagic feats to it (there's a lot of potential metamagic feats that can apply to this spell).

Enlarge Person
--Put it on your party's BSF during the fight, stand back and watch as he lays waste to the enemy. Limited out-of-combat utility outside of very niche situations.

Expeditious Retreat
--Double you speed, and give yourself an effective +12 to Jump checks. Funnily enough, that's actually a better bonus than the Jump spell gives you at this level.

Feather Fall
--This spell saves lives if the unthinkable happens and the group starts falling a long distance. Falling distance is no joke, so don't treat it like one.

That's 13 spells (all of them Core) and you get 12. I would suggest dropping Disguise Self if you're not interested in putting on disguises. If the other options don't seem very interesting, you can always select spells from outside Core; while those spells aren't available on the SRD, I know a place where you can find them; I'll send you a link off-site.
