Just a heads up, Scott Kelby has a great book called "Light it, Shoot it, Retouch it" that focuses on studio lighting. Easily one of my favorite photography books. The layout of the book and the way he shows how the shots are created is far better than any other book on studio lighting / strobe use that I have ever read. I used a similar kit to the one you bought with a few other books and never really got the results I wanted. I recently upgraded to strobes and Kelby's book and I'm getting MUCH better shots. I attribute a little bit of it to the strobes, (hot lights can only get so bright) but much more of it to Kelby's help and a lot more practice.
Also, your daughter, unless she is a REALLY good sport, is likely to hate you soon. You're going to have her sit there and pose for hours, while you play with settings, moving lights, etc. My girlfriend is not usually thrilled when I bring the strobes out. I found taking her out to a nice dinner afterward helps a lot :-D
Enjoy your new setup! It's an entirely different ballgame!
