No and no. Use the source, and it's pretty straightforward.

Yes, they help better your precision. Not a "fix-all-cure" but then,
nothing really is;-).
They calculate a "fuzzy" digest of each message and check if they are
in the "known bad" category... And if found, SA will use them to add a
nice point value or so. If more than one match, DIGEST_MULTIPLE come
into play too.

My copy of the book is to old to judge from... I'd image not more than
in passing though.
Read the wiki (both the documentation section and the maq)... You'll
find both useful info and links there.

Policy for how a digest end up in the database, and implementation
details. If you really want to know, go read the wiki (and their
respective sites).

Good, that means you'll be able to use all three without infringing
any licenses.

BTW, this is the place to start looking for info: http://wiki.mailscanner.info/
