I've been playing blues for nigh on 25 years now, I can't add any suggestions to listening recommendations as the above will keep you busy. All I'll add is find the groove, lock in with the drummer and let the melody instruments take the lead.
Also know when the leave space and when the bring in some dynamics. Well played blues is the best feeling in the world, but melody players do tend to get a little over excited and it can fall to the rhythm section to pull it back and introduce some dynamics. Try not to "over rehearse" it as the joy of the music lies in it's spontaneity.
Alternatively ignore all of the above :-)
