This is also approximately how I manage this (or did, my key broke
yesterday and I haven't got a new one yet).
The only difference is that, rather than symlinking ~/.gnupg, I symlink
~/.gnupg/secring.gpg; that way, I can mount the USB key read-only, which
allows me to safely remove it while still mounted; my trustdb and public
keyring are synchronized in other ways.
