Shawn, I don't know the exact look you're after, but for a single shadow, you could make your main light SO DIFFUSE (ie, real large source) that no shadows are apparent; then using a spot on her face will produce the only obvious shadow.(posted 8805 days ago)A second option, assuming you use an umbrella for the main, would be to mount your spot projector within the span of the umbrella; ie, a harsh light source within a soft source. Now, the question is how? For the B&W, IF you have a slide projector, you could set it up within the umbrella's coverage and use a cutout (slide) to limit the spot size. Use shutter time to balance light levels with the umbrella flash.
For the color, you COULD rig up up a small flash unit with some lenses into a projector. However, don't consider this for right now unless you already have a good general understanding of how a projector works optically.
FWIW, Norman Enterprises ( http://www.photo-control.com/norman.htm ) has a projection flash head called the Tri-Lite (P/N TL-2000?) that can take up to 2,000 WS power and is focusable with slides. I think it's out of your price range (~$1,000), but it demonstrates the general idea of what you would want to rig up. Norman also has fresnel lensed light heads.
