No need, but strong advice to have.

Did not do it myself, but should be feasable.

If you want to have high availablility in case of failure of the director you
heed heartbeat. Otherwise on failiure of the director all services are not
available any more.

The is a ldirectord resource agent in version 2.1.3 of heartbeat. So
1) start ipvs and state sync on both nodes.
2) Let heartbeat control the virtual ip address and the ldirectord.
3) Have fun when you see a download stopping for agout two seconds when one
node of the heartbeat cluster fails.
by the way: There is also a XEN resource agent in heartbeat. So you can
control your virtual machines from the cluster.

See last points. Your heardware, beside the second interface seems to be fine.
Also use an additional heartbeat via serial interface.

Use the GUI to play around and learn heartbeat. But do not get frustrated by
errors and failuries when working with the GUI. CLI works!
DO NOT USE the GUI in production environments!
