There have been lots of good responses to this but I'll toss in anyway.
Some experts suggest scanning at 150 dpi, which is (usually) a multiple
of the scanner's native resolution (600, 1200, 2400 etc.). An added
benefit is that this "extra" resolution will let you crop your image for
the web without dropping below the 72 dpi threshold.
Photoshop can batch process your files for the web once you have them
cropped and tonally adjusted the way you like. Gary Miller rightfully
pointed out that jpeg compression (and smoothing) decisions can vary
image to image. You can still save time by grouping your images
(landscapes with lots of sky, foliage closeups, portraits, etc.) so you
can batch process each group with its own set of "save for web"
parameters. This is a real time-saver if you have lots of images to
process.
There's another handy thing in web design. Some software like Adobe's
GoLive has a neat feature called Photoshop Smart Objects. This lets you
save one Photoshop file from which GoLive can create your thumbnails and
enlarged web images. This is particularly nice because if you modify the
"original" image, GoLive automatically updates your thumbnail and larger
image. Very cool!
There is no benefit to scanning at more than 24 bit if web use is your
only intended output.
Good luck!
