Whether to read music and study theory, or not, is a hot topic on this forum I've noticed. It's all a matter of where you want to go with your music. Personally, I think you shouldn't limit yourself by not learning to read music. There are several books that teach basics of music reading. I currently am working through 'The Complete Jazz Method' by Jody Fisher. Also
this website gives lessons on how to read music. Good luck.
