Oh .....something else to worry about!
If I was that paranoid, I'm not sure I would be that confident about some parts of "the other side of the world" (particularly the obvious one in cyberspace).
Anyway, if you are serious then perhaps an enquiry to
this lot - a bit closer to home, in a bunker near you - may be able to point you in the right direction, albeit they look more 'major company' orientated. They certainly seem to have EMP covered.
Can't help you with the CD's; there seem enough scare stories around about relying on them solely for long term backup and storage, even before the EMP gets to them.
