macros are easy enough: start them with .de XX and end them with .., e.g.
start and end code example which I end up adding to most documents I write:

.de EX
.nj
.nf
.CW
.SM
..

.de EE
.fi
.ju
.LG
.R
..

There are quite a few books, see http://www.troff.org/ , my favorite is
"Document formatting & typsetting on the UNIX system".

I really don't know how you would add line numbers, if you are lucky there
may be a well-known macro which is run at the start of every line...
