Don't remove the installed package, downgrade to the version you want. This
might still result in packages being removed due to them depending on a
certain version or greater of X.

If Knoppix adds that I would suggest moving from it to using preferences.

Unless otherwise configged, yes, that's what it'll do.

Had examples in the other reply, look there ;-).

Yup. It required some effort, but I've done it several times. Pin the dist
you want at over 1000.

Makes it fun. Much better than when you're making sense ;-).
