I always make the scan at a larger size, 2000 dpi at least. I then do cropping and other touch-ups in other programs. If done on a reasonably large scan, the effect of ICE is very difficult to see. To be honest, I have never made a scan smaller than 2000 dpi, so I don't know what effect that has.
Nikonscan's setting tools for dpi settings are not the most obvious (unless you read the instructions - something I have a tendancy never to do
For one thing, first make sure the image is by default flipped to landscape. Under Layout Tools, click the appropriate arrows to do this. The setting should automatically be saved for the next time (just like everything in the Tool Palette).
Now make sure you have the entire scan area selected. if you have a little box selected in the preview area, the easiest way is simply to drag the borders to the edges. The "Keep This Crop" setting should be greyed out and stuck at 5782x3946, the maximum scan area. Ignore it from now on - you don't need it.
I set the Resolution to 403 pixels per inch because I have a 4x6 printer which works at this definition. Put whatever you want here - if you intend to print pictures, set this to the resolution supported by the printer.
Under "Keep This Output Size", you should have the same proportions as 5782x3946. Enter those numbers to start with.
Don't ever touch the "Keep This File Size" control. It's dynamic.
After all this, you should have a Tool Palette that looks like this:
Now, setting the resolution should be easy - just slide the "Scale" slider back and forth. I set it to around 500%, which equates to about 2000 dpi.
Does that help?
