Specific to the question of books and approaches, I highly recommend David Allen's "Getting Things Done". Don't be put off by the shiny self-improvement wrapper -- once you get under the surface, this is way more pragmatic than any other time management system out there. Allen coaches business executives, CEOs, etc. -- people with seriously disfunctional situation-caused ADD (300+ emails a day).

In one of his seminars, he explains why he evolved this system as follows, "Because I'm the laziest SOB alive...". In reading and listening to his stuff, I realized that he put the "laziness, impatience, hubris" philosophy at the core of his system -- I think anyone who's into Perl and looking for time management help should check it out.
