Yes, it will attempt to backup all connected drives that aren't specifically excluded.

Yes, if you select both as backup disks in System Preferences > Time Machine > Select Disk it will backup both. Not at the same time but first one, then the other.

I don't think I made my self clear. I want to back up my computer and my external harddrive plugged into my computer, both to another portable hard drive I have selected?
