Reciprocal gyre (SC) is a decent abjuration spell that deals damage. It's not the greatest, but it's something. If you feel like expanding the focus slightly to divination/abjuration (the "pure" schools of magic, as it were) you might include the various chromatic/prismatic spells. That gets you good defense and offense, although those spells are mostly high-level. Also, have a look at brain spider (SC). It's a cleric spell normally, but might make make sense on this list.
I'd recommend you consider Speak Language as a class skill.
Spellsight III: I think you meant greater arcane sight.
