Las's version is impressive. One more tip:
It's generally best to do as much perfecting as possible in the scanner before it even gets to PS. Your scanner interface may have a box for "descreen" (like mine) or maybe there's a paper or print type setting somewhere.

Or if you don't have grain surgery try this
Image> Mode> LAB >Channels> Lightness
Use the Dust and Scratches filter set to about
Radius 3 Threshold 0
return to RGB mode
to Sharpen Image use:
Duplicate layer
Filter> High Pass
Radius about 3
Blending mode> Soft Light
Flatten
You could try Filters> Noise> Reduce Noise after this step
This method may not produce the results of grain surgery, but I've used it a lot and found it to be effective

IMHO, scanning at 600dpi for an image that will appear on a monitor that (is most likely) displaying 72 dpi is a little overkill. It's referred to as "overscanning" (I'm sure that there's a more technical term for it). I'd try dropping the scanning resolution down to maybe 100, 200 dpi at most. If it'll never be printed, then you don't need to worry about the super high resolution. Overscanning usually picks up flaws in the paper and/or print itself. Other than the overscan issue(?), it looks like what Gallo_Pinto said should fix the problem. I think he hit this one right on the head, it's a scanner adjustment. Seems as if there's a filter (or lack there of) that needs to be turned on or off. I'd play with the settings on the scanner first, and go from there.
