Is my Pre-2012 CD useless? Registered on Origin under my old Account.
Do I have to hunt down a new pre-2012 Sims 3 base game CD if I want to go V1.67? Have I pretty much killed any chance of using my 2012 CD of Sims 3?

You don't need to have this CD registered to your new account, unless you'd like Origin to manage the installation. Which is, I believe, exactly what you're trying to avoid. In fact, I think people usually do disc installs while entirely offline so that the old download manager can't upgrade itself to Origin while they're not paying attention. But if you'd like to cover all your bases, you can ask someone from EA customer support to merge your two accounts, and then you won't have anything to worry about.
