You can use linum.el to add line numbers, and by customizing
linum-before-numbering-hook and linum-format you can make it to show
certain lines in a different way. If you've got Emacs from the CVS
repository, you already have linum.el; otherwise, check

There are several libraries which can help you do that
(colum-marker.el, col-highlight.el, vline.el, etc.). Take a look at
