The Charlie Parker Omnibook is a pretty good jazz equivalent for a classical etude book.

Firstly, forget "bebop scales" - for the reason Jens says, they're a theorist's invention. (The principle is easy - just insert a passing chromatic somewhere in a standard 7-note scale in order to make 8th-note scale runs land on chord tones. That's if you're playing 8th-note scale runs of course - otherwise, not much use.)

Secondly, learn some Charlie Parker tunes and solos. Easy enough with the Omnibook (that one's for alto but there are Bb and C versions too). It may not be 100% accurate, but is a great reference. You'll see he mostly uses arpeggios, but other bebop tricks include enclosure (approaching a chord tone from the notes either side, often chromatic).

I.e., don't think scales at all - think chords (arpeggios), maybe including 9s or b9s where appropriate. And add chromatic approaches, from above or below - but always targeting chord tones.

And above all, think rhythm. That was Dizzy Gillespie's advice: rhythm first, notes second. That's where the word "bebop" comes from after all - vocalising jazz syncopation.

This book (Patterns for Jazz - Jerry Coker) got me through high school, and I still use it when I want to get my chops back into shape. Depending on your current level, it's good to read through some of these: Lennie Niehaus Jazz Conception for Saxophone -- good to get a sense of phrasing and articulation. And of course there's the Charlie Parker Omnibook which now comes in a few different keys (though I'd stick with the Eb version for the fingerings to make most sense). Aebersold's great, as well as auto-accompaniment software like Band in a Box. But your best bet is to forget your ego and go play with people who are better than you.

Bloomdido/Moose the Mooche were my first two. Also if you're serious about playing Parker (or about improvisation at all for that matter), go buy the Omnibook here. I can promise you it will be the best $15 you will ever spend as a saxophonist.

If you play alto sax, aebersold's book of charlie parker transcriptions is essential, it's called the omnibook
