I found
Streetsmart Guide to Valuing a Stock very useful. Using the book, I was able to build a spreadsheet duplicating the authors' model. Very good guide to how a Free Cash Flow valuation works. This came in very handy for working with and building other valuation models.

I also second Vern's endorsement of Prof. Damodaran's work. Here's a link to his pages:
