There was a .prj file in the zip archive you downloaded. That gives you the projection...

I changed the projection in my map file to 900913. Initially I got a new error that, "msProcessProjection(): no options found in ‘init’ file". I checked my epsg file in /usr/share/proj/epsg. It did not contain a definition for 900913. I found a definition online. I added it to the end of my epsg file and it cleared up the error. <900913> +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs 2. Updated my wms_onlineresource field to replace that incorrect trailing ? with a &. Once those changes were made, it worked. I have one follow on question, *how did you know that epsg:900913 should be used from looking at the shapefile?* Is there a dictionary somewhere that says Google Mercator=900913? Here is my corrected map file per Steve's direction.
