I have been messing around with jazz for a while....but now I want to get really serious about it.

What kind of things should I look at? Any book reccomendations?

I really want to get serious about jazz. My theory knowledge is OK...(ABRSM Grade 5) but I have trouble applying all of it to guitar.

I listen to a lot of jazz and really like:

Joe Pass
Wes Montgomery
Emily Remler
Al Di Meola
Ella Fitzgerald (is she jazz??)

Any help??
