Blues Bass by Ed Friedland is a good place to start learning the blues. And since a good deal of the jazz created during the 60's is blues based, it should allow you to eventually transition towards jazz.
In my own musical journey, I was pretty obsessed with learning jazz right away, and I struggled. A good friend of my said, "Forget all that Jaco Pastorious stuff and learn to play the blues." It was some of the best musical advice I've ever gotten. So I did that, and joined a pretty good blues band, which was my first band. I was lucky to have an excellent drummer who really helped me with my time and creating a pocket, etc. After that, I played in a Top 40 band, an Alternative Rock band and a couple others.
By the time I started with my current jazz trio I had been playing for about 3 years, but I was still a novice. It took a while for me to understand how to execute the form. I was ok at it, but it was hard. Even Miles Davis had considered quitting jazz, because he said it was really difficult. But I stuck with it and my bandmates were very patient. Jazz is fun now, but it wasn't for a long time.
Music takes a lot of effort, but you have to love the effort to be any good at it. I had a really good bass instructor and if I had tried to teach myself all the things that form the foundation of music, I don't think I'd have made it. I recommend you look into getting a good teacher. Books can't help you when you have questions.
