Yes, I have used SSH with and public-private key pair with no password. It works great if you don't mind the risk of someone gaining access to your machine.
For example, if your machine is already password protected (like a login password), you might consider the benefits of a key pair without a password if you login to a remote server with SSH often.
Yes, you will have to regenerate keys if you change IP address on either the server or the client.
I don't think there is an easy way to pregenerate keys, but you might find a way. If you do, please post how to do it.
