one method I use for selectively removing grain is to use the dust and scratches filter (Noise / dust and scratches). I normally use a low radius with quite a high tolerance, but it's whatever is best with this filter. Sometimes this filter takes out too much highlight, and is no good.
A workaround for this is to apply the filter selectively, and use the history brush - apply the filter, then in history pallete click on the history box on the left hand side, on the most recent step (the filtered image). Then select the previous step in the history pallete. This will now allow you to use the history brush to apply the characteristics of the selected step in the history pallete to the unfiltered image on the screen. This has saved me many times.
I have read a couple of photoshop books and I haven't found a better method. Sorry if you already knew this tip, it may be that you have tried to apply this and were not happy with the results - it may not be an ideal solution - what does the image look like?
Anywho, hope this helps
Cheers,
Will
