This one, at least, is very easy and is not language-specific. First, go into Preferences. In the General settings, check "Show right margin indicator" and "Highlight right margin". Next go into the View menu and set "Wrap Column" to 72. Make sure that "Soft Wrap" is *not* checked. The result is that you'll get a thin line between columns 72 and 73, and all columns past 72 will have a shaded background.

As for the rest, I'm afraid I can't help you. I'm quite happy to say that I haven't touched F77 (or any other FORTRAN dialect, for that matter) in almost 25 years now. Back when punchcards were only slightly outdated.  :-)
