I just purchased a book and Video set called FretBoard Theory... It puts together several different theorys I have been working on for LONG time individually.... I give FretBoard Theroy a 110%, it has added to a lot of pieces to the puzzel... I have got 10X out of the book for what I paid; then combining all the songs on this site with the systematic FretBoard Theroy I feel like Im on a whole new plane in my playing.
