I will second the motion of forwarding to documentation here. It appears you have a lot of the same questions that I had when setting up my environment. It will all come to fruition after stepping through it slowly. This is not something to piece together if being used for your production environment. You'll miss something important and have to deal with it eventually. If this is a project for your job that needs to be rushed along, explain that setting it up correctly in 1 day is not really going to happen. That being said, your google searches will land you in fedoraproject and redhat docs. Both are usable and will get you where you want to be. After setup correctly, the replication is super simple in the DS interface.
