Just the list is fine. Often we CC mail's for sake of speed to the original

Transparency positive film and reflective prints are quite easy to profile.
Currently there are no profiling tools for negative films although I've
heard that they (ANSI?) are working on t now. Negative scans can use LUT's
(look up tables) that do well in establishing densiometric colour
equivalents. Most say Hammerick's VueScan scans better at negs than all
other acquisition apps. You could try it.
Scanning negatives with the auto ranging controls in the leading
applications brings you to a ballpark scan. Fine tuning is slow however as
you should manually tune the three base densities of the film. The base
densities change with each film and amount of exposure.

Yes. It works well even by email. Putting the profiles into the correct
workflow though is much slower than the creation of profiles themselves.
Many of the profile app vendors also remote profile by email. See
chromix.com for info on this and also he has a library of profiles for
download.

Yes but not for negative films. Here you best to have a calibrated and
profiled monitor and adjust by eye. The most important aspect to digital
imaging is screencentric so that's really where to start. I think you said
you have an iMac. They are a little harder to calibrate but they can be done
just the same.

Personally I'm not a fan of those as I'm too colour critical but for amateur
uses maybe. For the printer side you'd need to scan an A4 so your Nikon
wouldn't make print profiles.
