I\'m a totally blind individual who would like to learn more of the theory aspect of computer science. I\'ve had an intro data structures class and the general intro programming
You might find the Experiences of a Blind Computer Scientist a good read.
MIT's Open Courseware would be a good resource for you with the amount of videos/audio they have.
Really though, for the core computer-science topics I find it pretty hard to beat some of the better textbooks out there. Some offer digital versions of their book with purchase and some don't. For those that don't, I would just purchase the book and then download via a torrent site a digital e-book equivelant. Since you already own the book I don't think this would be a major problem.
