Depends on what you're trying to do.

Yes, it seems so :) Why don't you start by reading the HOWTO? If you
have realservers with a public IP and your director with a public IP in
the same subnet, you could try setting up LVS-DR. It requires for you to
add a loopback device on the realservers and, depending on the OS, solve
the arp problem.

LVS-TUN is probably not what you want. Heartbeat and ldirectord are used
mainly for when you're setting up a failover cluster with 2 or more
directors. The best way to learn LVS is to set up the IPVS table
manually so later you know what ldirector automagically does for you :)
