Wow, SSH tunneling appears to be simpler than I originally thought. I believe the answer to both your questions is, Yes.

As I understand it now, the command "ssh -f <user>@machine2 -L 1000:127.0.0.1:2000 -N" essentially means, forward local port 
1000 through the remote SSH server to remote port 2000. Responses from remote port 2000 should follow the reverse path and be 
encrypted as well.

Here is a useful article I found on the topic:
