Thanks for your help Christopher. I was able to get this working by
switching my gml version out and reprojecting to my base map coordinate
system. It is working well now. :)

^^ Is this really the start of the file? Nothing else? This is clearly a
problem, because there are no namespaces defined here, so this is invalid
XML. It seems like something here is misconfigured on the server, so I'd
take this to the GeoServer list and see if they have any ideas. I know
that
the GML support in OPenLayers was built entirely around GeoServer, so
there's
no reason to believe that it shouldn't/couldn't work.
