I need to know, if when using an offline computer to sign transactions with Armory; whether that computer (offline computer) has to be constantly synchronized to the internet (and thus not be a true offline computer), or whether I can setup armory and Bitcoin Qt on a computer that is NEVER connected to the internet (and thus not synchronized to the blockchain) and just sign transactions that way.

I have a netbook I can keep offline and just use to sign transactions; I just want to do this as safely as possible.

I would also like to know, if when I create a new wallet in armory, if I make a paper backup of that wallet, will all the adresses I create within that wallet in the FUTURE, will also be backed up. Or do I need to make a new paper wallet every time I add an adrress?

I appreciate any input.

Noob.
