You have a lot of redundancy in your spell list. Scorching Ray and Acid Arrow? Pick one (scorching ray) and drop the other for mirror image or some other defensive spell.
Fireball and lightning bolt? Pick one and then get the Energy Substitution metamagic to see how far that takes you. That gives you a new 3rd-level spell to pick as well (like fly).
As for 5th-level spells, as others have said, empowered fireballs are your friend. I would get a more utility spell like a hold monster, baleful polymorph, or overland flight (9 hours of flying isn't too shabby).
Just some thoughts.
