Has anyone written a RECENT beginners tutorial about DIGITAL satellites? I don't need to learn how to track SO-50 with my HT, but I do need to know about configuring TNCs, virtual or otherwise.--

Not sure about complete beginners guides but because pretty much all
digital sats today (not counting telemetry only sats) are APRS style
unproto digipeating and not store and forward like it was years ago APRS
is a good starting point to look into.
One site you could have a look at is the APRS Sat page from WB4APR, it
is a bit messy because Bob likes to add info to the page rather then
completly rewrite as information gets updated.
Most people prefer to use UISS as the main software because it has been
designed specialy for the task.
For virtual TNC it is recomended to use UZ7HO soundmodem
http://uz7.ho.ua/packetradio.htm or direwolf
Both preform better then most hardware TNCs especialy older ones that
have started to drift in tones.
