Ben,

My understanding is that the core problem is that you are using gdalwarp
and it is failing.  Is that right?  If so, could you provide the gdalinfo
report on the input file, and the exact commandline for gdalwarp that
you are using?

When creating a new TIFF or GeoTIFF file you should be able to use the
PHOTOMETRIC=RGB creation option to force the output file to be marked
as RGB.
