Thanks a lot everyone. I didn't know about the CQL_FILTERS parameter on WMS requests. Thanks Simone for the very detailed document going through exactly the issues we are having!
As for the custom projection, our choice of re-projection was not only taken because of our difficulties with Geoserver, but mostly because our collaborators never know how to deal with Rotated Pole... And for SLDs, I see many interesting options in the document. But I also see that Geoserver supports ncWMS's extensions, which might be just enough for our simple colormaps usecase.
