Hi David, 1) I think you already got an answer for this - the one thing I'd say is that the graininess might be a poor source resolution rather than the compression, or due to resampling. Anyway, I'd be interested to know if the compression helps solve the problem.
2) I'd try the RasterInterpretationCoercer. From what I know of raster you can use this to change an RGB type raster to a greyscale (GRAY8 or GRAY16).
