This [CLICKY] is an excellent article on flamenco, with a general explanation of its structure (Wikipedia really came through with this one). Among other things, it gives a good rundown of the structure of some of the forms in terms of rhythm (sometime fairly complex) and harmonic structure (not really too complicated when you get the hang of it).

The key to those blazingly fast scales and runs is practicing them very slowly until you can do them perfectly, then speeding them up slightly and practicing them again. And again. And again. Until finally you can do them fast and clean.

Trying to play them up to speed at first is a good way to braid your fingers….
