I'll 2nd the Andy Green stuff, and also just getting a good real/fake book and learning a few standards every week, learning the arpeggios and chords and really learn how to solo through them..
propperly pronouncing the the 3rd, 7th, 9th & 13th chord tones, and every single day practicing your fretboard, learning what ever voicing of every chord sounds like and knowing your harmony theory inside out. it's the only way to become a jazz player and it takes years of dedication.
