Agreed with webrunner5, make a Human Mage. Stick with the Fire pets while leveling and let them do most of the heavy lifting (just make sure to at least do 1 point of damage to the mob or the pet takes a big chunk of XP).
Save the bone chips and pelts you find and sell them for some starter gear. Look for cloth armor with +mana or +int. Don't spend a bunch on a weapon, you wont be attacking things fairly soon.
Head on over to the p99 wiki page and click on the Magician link, there is a lot of good information there. Also check out this link for a good leveling guide.
