it looks like none of your question is really corosync related (so I'm
CC'ing linux clustering <linux-cluster at redhat.com> (this is really
better list) but I will try to answer at least some of your questions.

You must make sure that NO nodes has this address assigned. IPAddr
resource will take care to add ip to interface.

I don't think this is supported by any resource script.

Every node must be able to fence any other node. So you have to
configure fencing method for every node.

In theory fencing is not needed as long as you are not using shared
storage, but it's still better to have it.
