sight reading and chord construction are two different skills. you can read and still not know the first thing about chords. i strongly urge you not to put off learning it.
btw, i think you're confusing the term "sight reading," which is reading a chart for the first time, with just plain "reading," which sounds to me more like what you're doing.
i also highly recommend getting a teacher who knows about jazz concepts and applying them to bass. that will help you get some more focus to what you're doing. you're on the right track by your willingness to learn academically, but i feel like you're making a few unqualified assumptions along the way and maybe don't know the best path to follow. if you can swing it, a good teacher will get you even more on the good foot.
I agree. Wish I could afford it right now. As it is, it's just me, books, and the internet. It's working, although a teacher could be of great use to me. Hopefully in the not to far off future I can get to that.
