You can also just manually create a few shapefiles to play with.

Correct, TIGER will be releasing its data in shapefile format shortly 
though.

See section 4 of that page 
(http://mapserver.gis.umn.edu/docs/reference/utilityreference/tile4ms/). 
  You use that index in that ONE layer, and MapServer will draw all of 
the associated SHP files that are 'indexed' in that one index file.

If you find a section of that page unclear please let me know and I can 
modify that page.
