That was a pretty good summary.  If you're starting from scratch,
you might as well look at 100baseT cards and hubs, if you already
have some equipment, it's a trade off between 10baseT and thinwire
coax.  10baseT hubs are much cheaper than they were initially and
if everything is close enough to just use the modular cords between
one hub and all the systems, installation is trivial.  Thinwire
avoids the cost of hubs and it's sometimes easier to string one
daisy-chain of coax than a star arrangement of twisted pair, but
the connectors are a pain, pre-made cable expensive and it isn't
upgradable to 100MBit...

The book recommendation is good, there are others but one thing to
note is that at the outset of a new standard, there are usually several
different ideas and compatibility problems, that gradually sort out as
one standard prevails over the others.  As a result a boot that tries
to be comprehensie usually make it seem a lot more complicated than
it really is in day to day application.
