A few years back I picked up a guitar magazine with an article by Steve Vai called "Freak Show Excess." It has several pages of intense excersizes covering all manner of guitar playing as well as training tips and insight from Vai himself.  They cover a program that Vai believed would help make someone a much better player with practice of his key concepts.  It might make an excellent base for a set of guitar training excersizes.  I lack the skill and fluidity to play them myself, but if anyone would like them to start a project of their own, I can provide you with them.
