The documentation index has a few entries for "SSL". Here are some
useful links for 8.0:
http://www.postgresql.org/docs/8.0/interactive/ssl-tcp.html
http://www.postgresql.org/docs/8.0/interactive/libpq.html#LIBPQ-CONNECT
http://www.postgresql.org/docs/8.0/interactive/client-authentication.html#AUTH-PG-HBA-CONF

You could add "sslmode=require" to attempt only an SSL connection.
If the connection should always be encrypted, then you could edit
the server's pg_hba.conf and allow only "hostssl" connections. In
that case you shouldn't need to specify "sslmode=require" when you
connect, although doing so serves as a safety measure against
pg_hba.conf misconfiguration, and as a reminder that the connection
should be encrypted.

Yes, assuming you've successfully negotiated an SSL connection. To
be sure, you could use a sniffer like tcpdump or ethereal to look
at the traffic.
