Jack I have a similar set up. I use clip on lights attached to two old tripods that I don't normally use and have a third set up over my table, trying to mimic a three light set up.
The clothespins are use to hold in place deflectors or I will put paper in front of the lights to soften them up a little. Because the lights I use run so cool I can put plain paper in front of them and not worry about starting them on fire, however keeping safety in mind I don't leave them on for a long time just in case.
Another Nikonite who is a strobist recommended the Daylight 6500k bulbs. The 6500K will help with your white balance and I have been told it is a purer white light. I have found this to be true. As for the wattage on the lights I just guess at it.
I would play around with this more and maybe get a set of lights at a lower wattage or put dimmer switches on each lamp to control the lighting a little more, but I'm look to pick up two more Speedlights in the coming weeks and feel no need to take this any further than I have.
