IMO it is best to use ssh-copy-id <host> to transfer your public key. I have begun using: ssh-keygen -f "/home/<my-uname>/.ssh/known_hosts" -R "<remote-host-fqdn>" to remove ID's from my local .ssh/known_hosts file.
The advantage of the first is that you don't accidentally copy your private key. The advantage of the second is that you don't accidentally remove a key that you didn't want gone.
