Hi
I would configure config syc, failover network and mirroring ips on both devices prior to doing any HA handshakes between the two boxes. It is this config that determines how the boxes talk to each other.
You also missed out the most important step which should be No.1 - take a pre-change backup!
As long as you sync the config the correct way then you shouldn't overwrite anything.
