Well, foremost one must know and constantly be reminded that Jazz is an aural art .Cruising the internet for answers, reading books and articles are all good. But they are a supplement, not the main focus.
First off, listen voraciously. If you don't have the feel ingrained in your consciousness and body, you've missed the joint. So listen endlessly to recordings. Sing along to them, shadowing the rhythms and style. This is very important. Go to as many live performances as you can. Things happen live that may not happen when something is recorded for "posterity". Support and meet local musicians. Don't live in a vacuum.
Practice with Jazz play-alongs like Band-in-a Box, Aebersold, Garage Band, etc.
Start learning improvisation the same way. Go to jam sessions and open-mic nights, Play in groups,
I would start with Aebersold Vols. 1, 2 and 54. Once you've got familiarity with those, I would add The Goal Note Approach by Sheldon Berg.
Read as you go along, Jazz Improvisation by Jerry Coker and How to Practice Jazz by the same author. Read Jazz Biographies. Read and absorb a, IMO, invaluable source of information, Lost Chords by Richard Sudhalter
When you've got the chops, add Jerry Coker's Patterns for Jazz, and Elements of the Jazz Language.
Don't be a stranger to your recorder. You get valuable feedback from it that listening when you play misses, somewhat.
Keep in mind. The aural aspects keep dominance over the written and the intuition has dominance over the analytical.
There's more but if this doesn't keep you occupied for a few years, I'd be surprised. Good luck. Have fun.
