Julie,
That's the lighting approach I've used in the past and it works very well. You can apply directional lighting effects in PS and do a lot of skin smoothing with flat lighting.

It actually should be fun. She's bringing her best friend; Linda and Rose Ann will help with costumes, hair and make-up and all I have to do is look professional and not drool. I'm pretty sure I can handle that . And, yes, I'll share some of the results if James allows it .
