Probably you misunderstood something. The template file should be
referenced in the map file in the WEB section
TEMPLATE "relative path to template from the map file"
To display the map you can use an url 
http://your_server/cgi-bin/mapserv?map=...&mode=browse
or you can use a form with hidden input fields like the itasca demo.

Use shapelib utility shpinfo. See shapelib.maptools.org. There are other
useful tools in shapelib.

I can hardly imagine the extent of the world is 15 meters by 20 meters

Shape path should be absolute (starting from /)

This scale is nonsense. Remove MINSCALE and MAXSCALE. 
If you see the map try to find reasonable scales.
If you have only one layer no sense to use MINSCALE, MAXSCALE.
Put MINSCALE and MAXSCALE in the definition of a layer.
Read the MAP file documentation about them.
