Running OGRINFO on the tileindex file would return you the extent of the
tileindex which is also the extent of all your files.

Again, try OGRINFO to dump the contents of the shapefile and you'll see
if it's a point, line or polygon file and then you can set your map
layer accordingly.

See the OGR-HOWTO on the MapServer website for examples using OGRINFO.
