I think the Gaspar Sanz manuscript would be a good addition to this. It gives you all the basic chords, and then other ways to play the same harmonies in different positions. Also, it begins with easy pieces and moves up from there. It gives you most of the dance forms to play strummed, and then some simple versions to play "punteado". From there you can graduate to more complicated music if you like. If you like Spanish music, you can't go wrong with Gaspar.
You can find a PDF of much of the work on Yar Kislov's Page, here on this site.
