Hey Themage, you might want to check out the GE Reveal line of incandescent bulbs. They fit into a standard light socket and, with a quick trip to the hardware store, depot, etc., you've got a lighting kit that will work great with your new digital camera.
Whip out your instruction book and see if your camera allows you to do a manual white balance. If it does, turn on your lights prior to your photo shoot and set your white balance beforehand. That will, in effect, make whatever light source you end up using become the true white value in the photo. That's why you sometimes see video guys shooting a white card before taping a news or sporting event.
One of the benefits of using lightbulbs to shoot models is that you can instantly see what sort of lighting effects you'll be shooting. You can make subtle changes to the lighting by using reflectors made from white index cards or crumpled and re-smoothed aluminum foil. The crumpling helps prevent hotspots, by the way.
Hope this answers your question and gives you some cheap alternatives. I use a professional electronic flash setup to shoot my models (I'm a photographer by trade) but can achieve almost the same guality (at least for internet posting) at home using my trusty Reveal bulbs.
Give it a shot, practice makes perfect and, with digital, costs you nothing.
