My friend gave me 5BTC on a USB, and walked me through the process of installing wallet software and importing the wallet to the compter. If I delete everything associated with bitcoin on the computer and only keep the USB, does that count as a cold offline storage wallet? As far as I know, it is the only copy of the wallet in existance.

No, with a true cold wallet, the private keys have never touched an online computer, ever. As soon as they do, it becomes a hot wallet (because the online computer could be compromised, even if the chance of that is fairly low).
