Stainsor's answer provides some good ideas -- especially on using the photocopier -- however there's one additional tip I'd like to share that can make a big difference: black paper. Use a sheet of black paper behind the page you're trying to photocopy (or photograph) -- it'll help eliminate any bleed-through from the opposite side of the paper you're trying ...
I don't know exactly what you mean by "docket", so I am just thinking of it as a faded document. Since you just want to make it easier to read, I am assuming that color reproduction is not important. I'm also assuming you are trying this on (or have access to) a Xerox style photocopy machine. I'm also assuming you are not super familiar with photographic ...
To capture as much detail as possible I would say expose to the right (although this may not be necessary) and make sure you have enough nice even light on the document that you can use your camera at its base ISO. To process the image, I would play with the curves and levels. If you don't know what that means then just using auto levels will probably do a ...
A big-hammer approach is jhead's -purejpg option, which, according to the documentation: Deletes all JPEG sections that aren’t necessary for rendering the image. Strips any metadata that various applications may have left in the image. This is a cross-platform (Mac, Linux, Windows) command-line program. For example, if you want to remove metadata ...
I use jpegoptim for stripping metadata: jpegoptim --strip-all filename You could also open the image with Gimp and save it without the metadata.
Exiftool is able to do this using the -ALL= (see the linked documentation). You can apply better control on this, however, and I would recommend that instead of just deleting all metadata. If you're looking to remove the location information, for example, just use some pattern matching.
In order to project on to a sphere, you would need to apply a spherical projection to the image. The Spherize filter in Photoshop is a good place to start.
