Learning Classical Guitar

I've been playing guitar for about 10 years, mostly rock and metal and also a bit of jazz.  I know a pretty good bit of theory and can sight read a little bit (nothing too complex) and now I'm looking to learn how to play classical to prepare for an audition. Can anyone recommend a good book or two on learning classical and becoming familiar with classical guitar music? Also, any good pieces to learn that you could recommend would be appreciated as well as recommended listening. I don't really want a book for beginners, but rather a book for somebody who already plays guitar to learn a new style. Thanks.

Sight reading may be a must for a classical guitarist ... I was never too good on that on the keyboard, let alone the guitar (where you not only need to read notation but also translate the notes to positions on the fretboard).

Howard Wallach has written a series of books for classical guitar called the "[insert composer/era here] for Guitar". You've got pretty much everything there, like Bach for Guitar, Classical (era) for Guitar, Hanon for Guitar, Renaissance for Guitar... all sorts mate. And the best thing is, it is notated AND tabbed out, so it's really easy to learn the pieces. That's where I started out anyhow The Bach one I highly recommend.

I don't play personally, but my father has been playing in the classical discipline for most of his life.
Being able to sight read at a high standard is a must.

Although you already play guitar, the right hand technique of classical music is so different from electric guitar playing (in the traditional hold the pick sense) that it's not funny.
A lot of electric players make the mistake believing because they can play guitar already, the transition to classical wont be too difficult, but nothing could be further from the truth.
You will be spending A LOT OF time perfecting the right hand technique, seriously.
It's one thing to be able to play the notes correctly, it's another thing entirely to develop the technique to capture the subtleties and nuances on the instrument to make the pieces come alive.

I myself may be able to play all my major scales (and modes of the major scales) and harmonic minor scales, sweep picked arpeggios etc on electric guitar with ease and easily sit there and churn out technical death metal, but put a classical guitar in my hands and tell me to start playing some classical, and I can barely make it through even basic pieces, simply because as I said, the right hand technique is just another world entirely.
The right hand technique is really what makes it another instrument entirely.
