-Change the network binding order. Put HeartBeat second and SAN last (SAN was 2nd and heartbeat the last one)

I can sort of see why but I don't see this is to relevant, the cluster communication can still take place over the public network (the default setting)

-Assign fix IP values on the iSCSI initiator properties

Now this is relevant, your heartbeat and iscsi adapters should be set to not register themselves in DNS. Always provide fixed IP details to the initiator disk device connection to ensure the correct adapters are bound. My article linked above details this.
