(1) Since the destination is the Web, you probably can scan the 
photos at 72 dpi, since monitors will not show higher resolutions, 
and scanning at 300 dpi just creates much larger files.

(2) If it's a typical photograph, you want to output it as a jpeg, in 
order to preserve the many colors. Gif will reduce the colors to 256.


You might want to scan the photos in RGB Mode, and then convert the 
scanned images to grayscale. It's also possible to fine tune this 
process using calculations and channels, but that gets more 
complicated.
