Lighting Suggestions?

I am working on setting up a decent lighting setup at home. I purchased a Smith-Victor 2 Quartz Light 1200-Watt kit on Monday. I have the lights shooting into umbrellas and bouncing back onto my subject. I did a couple of shots on Tuesday and Wednesday night and I think I need one more light right above my subject.

Can you guys/gals suggest a light to compliment my current setup? I want the ability to shoot models as well as objects.

Here are a couple shots from my tests.
