Marc,

Rule of thumb is that you always want to scan at the optical resolution of
the scanner which may not be the highest resolution. Some scanner/software
combinations offer resolutions high above the optical resolution which are
achieved by resampling up the data from the optical resolution.

Other than a drum scanner your scanner will have a single optical resolution
and that is the ideal one to use. If that is too high you can safely down
sample in PhotoShop.
