Before I start to scan in my 1000 or so slides I was looking for a few tips from people who possibly have a coolscan.
if you plan on retouching the photos in Photoshop, sharpening should be left until the very end.
if you don't plan on retouching the photos in Photoshop, get a trial of SilverFast Ai. nothing beats it and it includes many powerful functions including sharpening.
I used SilverFast Ai with a Super Coolscan 4000ED for two years. unfortunately, the scanner developed FireWire problems (randomly losing the communication link with the computer) and it's been at the Nikon centre for the last 5 months. they still haven't been able to define or correct the source of the problem and my collection of film images remains in stasis.
