Here's a book I just borrowed from my library, Ted Gioia's How To Listen To Jazz ( https://www.amazon.com/How-Listen-Jazz-Ted-Gioia/dp/0465060897 ).

I'm only a few pages in but I've read Gioia's The History of Jazz so I think I'll be learning a lot.
Ken Burns has a documentary series titled simply Jazz.

On youtube you have resources like Walk That Bass, who also just launched a jazz piano website ( http://www.thejazzpianosite.com ).
