I would definitely get a more specular light instead of soft boxes. As for light sources, I've used strobe and hot lights only. I haven't used fluorecsent lights for portraiture. Maybe an APUGer might have some experience with them. I would get at least 3 lights. A main light, a fill light and a hair or a separation light. I have a set of Smith Victor hot lights and I recommend them. If you shoot color portraits, make sure the color temp of your lights match your film. I don't know how the color of CFL is. You need good skin tones with your lights. Good luck!
