I don't care what anyone says - 3.0 wizards were meant to use haste. Moreover, wizards in both systems are meant to use magic items that cast spells.
As a 7th level wizard you should get a wand of haste as you will be casting it on yourself first and then on every other party member of the battle (until you can get mass haste). Oh another thing, it doesn't make sense for a wizard to have anything but item creation feats as they can just research a metamagicked version of any spell as a new spell since they can know an unlimited amount of spells. So you might as well take craft wand. That way you can ensure you get the wand.
So round 1 you will cast haste on yourself and then another party member (preferably another spellcaster that can cast haste if possible). As mentioned previously, not only does haste give you the advantage in number of actions, it also is a buff spell in and of itself (a very good buff spell). You can start to see just why haste is so good.
Once the whole party is hasted, then you move on to the other spells.
Shield goes without saying - it is ridiculously good.
Not sure if they nerfed blink, but that is also one of the best spells available - especially for the party rogue or anyone with a ghost touched weapon.
Polymorph self if you are not using the nerfed version that turns simply into an AC booster. Alter self also works particularly well (again, with the pre-nerfed version)
Summon Monster to summon thoquas is also really cool (I believe they got rid of that in 3.5)
If you don't have a cleric - the empowered versions of the stat boosters are a must - moreover, you can just get a wand of the empowered version (x1 anyway) so that you are not using all of your second level slots.
Make sure you have scrolls of all the special circumstances spells - like knock, rope trick, elemental resistance spells, etc.
