With 1, you probably mean the mkgmap translation rules.  They specify
how OpenStreetMap node and way attributes are translated into Garmin point
and line types and attributes in the *.img file.

The TYP files are useful if you want to define custom map symbols and the
like.  If you think of the Garmin map data as a HTML document, the TYP file
would customize the presentation, like CSS and graphical images do for HTML.

If you find a good tutorial into TYP files and a nice set of tools, I'm
interested.  I use Debian GNU/Linux, and I am distributing a map of Finland
that I would like to be more useful for cycling (but still useable for
pedestrians and motor vehicles).
