Agreed. 4000ppi will also reduce any issues with grain aliasing, which can
be more of a problem at 2700ppi especially with Nikon scanners because the
LED lightsource is semi-collimated.

Disk space is cheap compared to the sheer arduous displeasure of scanning!

Agreed again. Save as 16bit TIFF because the greater precision is more
tolerant of processing, at least until you have completed all
post-production. If you aren't likely to want to make further changes at
that point the final files can be downsampled to 8 bit.
