I'm no security guru,
and don't really understood what you are trying to do,
but if you copy your $HOME/.ssh/id_rsa.pub to the other machine,
and add it to $HOME/.ssh/authorized_keys there
you should not be asked for a password.

Also I don't think there is really a choice between rsync and scp.
You can opt to use ssh with rsync, and I think that is the norm.
