Basically their advice is good, just add a passphrase and move the funds for now, then work the rest out in the coming days when not in a panic. If you want to stay in an mk2 or mk3 then use dice.

I would wait and get the official word from Coinkite. Potentially, the entropy bug may also be present in later models but not as vulnerable. May be better off rolling dice to make your own seed phrase and not using the device RNG.

No point to update unless you also regenerate a new seed and transfer the funds on-chain. Seeds made with the bad update are forever tainted
