Yes

No, nothing special.  As far as MapServer knows this is just
another raster file.  I will note that the XML file with the WCS
definition needs to be writable as the first time it is accessed
GDAL will fetch the WCS capabilities and add a bunch more detail in
the XML file.  You might want to even trigger this in advance with
gdalinfo to ensure things are working ok.
