I have a few book recommendations for you.
The first one is called Forward Motion: From Bach to Bebop
http://www.amazon.com/Forward-Motion-Corrective-Approach-Phrasing/dp/1410712141
Its a great book and really details a good line of thought in jazz improv.
The next book is a standard among true Jazz musicians and that is the Real Book 5th ed. You can buy the 6th edition real book in stores and it has all the copyright info in it but the 5th edition is the one they always go for in the jazz world. You will need to hook up with a few jazz musicians and ask them where you can find the real book. And when I tell you that its the drug deal of the music world, you will never fully appreciate that comment until you go and buy the 5th edition and see for yourself.
The last book I can recommend is a really good chord book. One that will show you several voicings of more advanced chords. The reason for this is simply so that you can follow the charts and know the chords and so that if you are playing with a big band or a piano you can get out of their way and play the chords in a different voicing to help clean up the sound. If you have piano horns and a guitar all playing chords in the same range then it just sounds muddy.
Hope that helps.
