Rob,

I think there will be a HOWTO addressing some of the WMS issues.  The 3.5
MapServer can now support reprojection of raster images that are read 
through
GDAL (NOT if read through the older TIFF interface!).

This works through the WMS interface, or normally if the projection of the
raster layer (as defined in a PROJECTION section) is different than that of
the output map being generated.  

Projections can also now be defined in terms of their EPSG coordinate system
numbers in PROJECTION sections.  These definitions can be properly reflected
back in capabilities documents generated by MapServer.  In any event, most
capabilities data can be provided in the map file via METADATA overrides.

PS. Some of the raster reprojection issues are addressed in:
