floppy would most likely be too small for the whole directory (depending
on how you use gpg). I auto-add all verified signatures to my public key

But in principle you are right: putting the secret key ring onto
removable media would be the thing. Personally, I'm lazy and trust the
protection of my password, but use a seperate (more short lived) private
key in the office with a network shared home dir.

Yes. But mostly you'll want to sign your messages with your key in
addition to encrypting them.
