Two node cluster by definition cannot use quorum - there is no way to
split cluster so that any part have majority votes. You can artificially
increase number of votes for one node, but that means if this node fails
no failover happens.

Whether heartbeat should use separate network or not is mostly matter of
preference and available hardware. It is not mandatory in any case.
