Hello,

There shouldn't be an issue with using OSM data (or OSM data/mapfile 
created through the mapserver-utils 
http://trac.osgeo.org/mapserver/wiki/RenderingOsmDataUbuntu) with your 
own data.  I know for the FOSS4G Benchmarking exercise we did have to 
make some changes to the mapfile, such as making sure each layer has a 
proper PROJECTION object, which you should keep in mind as well as you 
are mixing data from several data sources.

If it is helpful, the mapfile used in that exercise is available at 
http://svn.osgeo.org/osgeo/foss4g/benchmarking/wms/2011/mapserver/osm-google.map
