Correct.

Yes.  Open the DNS server computer's firewall to allow DNS queries.
Configure the other computers on your LAN to use the DNS server
computer's IP address as their DNS server.  It's as simple as that.

The complications are:  If your other computers are assigned addresses
by DHCP, then you have to put overrides on the individual client
configuration, or configure the DHCP server to say that *YOUR* DNS
server is the LAN's DNS server to all computers that ask it for an
address (I do this with mine).
