To use full power of scp you need to go through next steps:

1. Public key authorisation
2. Create ssh aliases

Then, for example if you'll have this ~/.ssh/config:

Host test
    User testuser
    HostName test-site.com
    Port 22022

Host prod
    User produser
    HostName production-site.com
    Port 22022

you'll save yourself from password entry and simplify scp syntax like this:

scp -r prod:/path/foo /home/user/Desktop   # copy to local
scp -r prod:/path/foo test:/tmp            # copy from remote prod to remote test

More over, you will be able to use remote path-completion:

scp test:/var/log/  # press tab twice
Display all 151 possibilities? (y or n)

Update:

For enabling remote bash-completion you need to have bash-shell on both <source> and <target> hosts, and properly working bash-completion. For more information see related questions:
