I think these are excellent choices for the level you're at, and Melf's Minute Meteors is an absolute I Cannot Live Without It spell, even once you start casting ninth levels, I think. It will deal damage to ANYTHING, you can toss 'em over and over, and that's really important for the poor mage stuck in the back. Also, they work great against Golems, especially the Adamnite (sp?) bastards you'll run into later, which are resistant to most magic and and even a lot of weapons. Later on, if you run across them, try to pick up a Staff of Striking for the cleric types and a Tasheron's Short Bow for your archer... these also will deal damage to the uber golems when most other things will not.
Best of luck to you, young wizard!
