I would use grayscale JPEG files (line art compresses very well, and
you'll get good download times). You also want to apply a reasonable
amount of sharpening and level compression to get your grayscales to
look more 'black-and-white'.  A very good reference on this is "Real
World Scanning and Halftones" by David Blatner.

You want to use grayscale in order to antialias the lines, thus giving a
perception of higher resolution (even though it's making fuzzy edges).
This all has to do with circles of confusion (explained in optics

You also want to make sure that the final size of the image will fit on
an average screen.  There are MANY people running 640X480 video on 14"
monitors, so for them, it is damned near impossible to view a large
graphic all at once.
