filmscanners: Scanning negatives for archiving

[kjaved@dubai.oilfield.slb.com (Khalid Javed)]

I have recently bought a Nikon LS2000 for the purpose of scanning my old 
negatives and archiving them on CD's. Could anyone guide me on the 
following issues:

1-      What resolution should I use for scanning?
2-      What file Format should I use to save?
3-      Any ideas on how to create a database like index to help search the 
archived negatives.
4-      Is CD-R a good medium to archive on?

Possibly this info is already available somewhere, in which case I would 
appreciate if you can point me to this information. Any Tips will be welcome

Thanks
