Yes, that seems alright.
I would actually take a photo of the QR code if you're only planning on having it printed on paper. Spill something on the QR code and you're screwed.
Take a photo of the QR code, save it as a JPG, chuck that onto an encrypted USB and secure it, just in case.
You can never be too careful...

Yes, pretty decent cold storage, just make sure you have the QR code printed or something
Downloaded a live TailsOS USB
Boot into TailsOS and download Bitcoin-QT Linux,
Disconnected from internet

Yes, thats a pretty good sequence. If I were being even more paranoid I'd say the TailsOS should never be connected to the Internet, so put Bitcoin-QT on a USB stick before you start, and install it from that. Check the MD5 of the Bitcoin-QT on your USB matches a trusted source and you should be good.
Reasoning: if you're compromised while on the Internet downloading Bitcoin-QT, anything you do afterwards is unsafe, unless you're physically disconnected from the Internet afterwards. You say "disconnect from Internet" but if that's just disabling the Interface in the UI, thats not good enough and a trojan could easily re-enable it.

I physically unplugged my router and there isn't any connections that I can connect to around here but yes that does sound more safer!

Sounds like a basic step-by-step guide to a coldstorrage yes.
Just make sure you write your priv. keys correct.
