In addition to much of what the other posters have said, I really like stepping through one line at a time along with the computer, as it forces me to think about one line at a time. Often I will catch the bug without even looking at variable values simply because I am forced to look at it as I click the 'next line' button. However, I don't think my answer will help you, Bill, because you probably have this skill already.
As far as learning resources go, I haven't used any -- I just explore all the menus and options.
