Buying a lighting kit - your thoughts?

I am looking at several lighting kits, including a 3 way umbrella light kit and a kit with 2 softbox lights.
Overall, which would be best for a casual shooter (really casual)? The 3 way kit has two umbrella lights and one light without an umbrella (and stands). The softbox light kit has just that, 2 soft box lights (with stands).
Also, if I did go with the 3 way kits, there are some with two light bulbs per light and some with one bulb per light, is it advisable to get the type of light that uses 2 bulbs or 1?

Thanks!
