Here's a few suggestions...
1. change the Aasimar fighter to Aasimar paladin
2. wild Elf thief to Teifling theif
3. I myself liked the clerics of Illmater, but whatever floats your boat
4. In 3rd edition rules there is no "dual classing", when you gain enough exp. to level up you can just put a level in ANY (not always) class.
everything else looks good in my eyes, hope you enjoy the game when you get the new computer

and as for your necromancy spells dilemma, all I could suggest is to have instead is a Drow instead of a Deep Gnome, just b/c of the Drow's magic resistance (don't have to worry about too many area of effect spells).
