I have recently installed Armory on my everyday PC, plus on another machine not connected to the outside world. I've created my wallet on the offline machine and a watching-only copy which I have imported into Armory on the onliner machine.
I have a paper backup of the wallet printed (immediately after installation) which I will keep safe in multiple locations.
I've transferred a quantity of BTC into the watching-only wallet.
Anything else I need to do?
