for the rythm of jazz i would say you MUST check out art blakey and the jazz messengers. the foremost group in the revolution of jazz that was hard bop.
if you want the guitar check out Grant Green, Wes Montgomery, Melvin Sparks for bop
Check out Grant Green, Wayne Johnson for soul jazz (an off shoot of bop which incorporates gospel and hymnal elements)
for cool jazz guitar (a west coast white derivative) Remo Palmer, Johnny Smith, Herb Ellis,
my favorite era is the hard bop / soul jazz era. My favorite trumpeter is Lee Morgon, fav sax Dexter Gordon and my favorite tech nerd math jazz guy is brubeck.
If you need anything uploaded for samples, I can hook you up.
