Hello Brendan, please follow the custom projection documentation from the GWC docs: <http://geowebcache.org/docs/current/configuration/layers/projections.html> and tell whether that's useful enough to create a custom GridSet.
As for getting the bounds to use, it's odd that the CRS reports both maxx and minx to be zero, even if that's ok given the projection. Looking at the following demo page it seems to me like they could be set to +- 3333134.0276, so <extent> <coords> <double>-3333134.0276</double> <double>-3333134.0276</double> <double>3333134.0276</double> <double>3333134.0276</double> </coords> </extent> <http://demo.opengeo.org/geoserver/web/?wicket:bookmarkablePage=:org.geoserver.web.demo.SRSDescriptionPage&code=EPSG:3031> Let me know how it goes.
