Hi jerlaw, I think a book to start with is the Guinness Who's Who of Jazz, with its details in alphabetical order about the greats of jazz.
I've got the Guinness Who's Who of Blues, which gives details of the lives and work of Muddy Waters, Billie Holiday. Fats Waller, B.B. King and the rest.
Then after dipping into the Jazz book you could decide who your favourites are for further reading.
Dave Brubeck is a favourite of mine, also Dizzy Gillespie's music. I know they are old-timers now, and I guess you prefer Miles Davis and John Coltrane, all good artists.
You probably already know about the Modern Jazz Channel on SKY.fm which is worth a listen.
Best wishes,
