I've found this book extremely helpful in mastering the classical guitar.
I've been playing guitar my whole life but within the last year made a concentrated effort to break new ground.
Recently I broke my left arm and found a lot of really good right hand drills later in the book and have been practicing them (about all I can do right now).
The author, Scott Tennent, has some videos up on YouTube also.

Great way to learn proper techniques and start burning them into muscle memory
