I'd go for scrolls of utility spells like mage armor instead of offensive spells. Since the scrolls will be at minimum caster level and minimum casting stat, you will get none of your bonuses to the DC.
I also agree with the wand of grease and/or mage armor. One of the best uses of grease is escaping a grapple: you can cast it on yourself or on a teammate.
A lot of times, you can get an offensive school/domain power like hand of the apprentice or force missile which will more than make up for your two spell slots.
