Ciao Michael, I am doing some clean up right now (some spare time :-) ) for the RasterSymbolizer code hence I can try to help you oua bit.
I would suggest that you first do a quick check on the tast unit class RasterSymbolizerTest inside the render module, org.geotools.renderer.lite.gridcoverage2d package. It contains some method to build (or parse from an SLD document) a style and to apply it to an input coverage. Afterwards we can try to build something that fits your case. Simone.
