By default the wizard does not have fire spells, but Flare and a one time use Fireball Scroll. The other default spells are Midnight Oil and Magical Poison Dart (you can change one of them to Burning Touch during character creation, though, in which case your use of the plural in spells would be correct).
The Staff of Magus spell will be blacked out if you changed to a non-staff type weapon.
