that means that there will be no more files from the repo's as they will be offline.
Correct! As soon there is a newer version available the repo's of the current version will be put offline. However, repositories for the LTS version stays online untill the end-of-life cycle of the LTS version has reached.

No and yes. It's not such a big issue if everything runs just fine and smoothly. There's not even such a big potential for security breaches or threats since Linux is lesser prone to viruses and malware/spyware. But keep in mind that you won't even receive updates for applications that are known for their high security risk, as example Adobe Flash. Those applications you have to update manually, but like you said, that's not such a big headache.

Even without regular updates Linux will still be stable and continue so.

things like FF will not longer be updated, so that will have to be done manually,
but that's no biggie
Nope. Updating FF won't be such a big issue. But ask yourself, it it really necessary? Most updates aren't even security updates...

which is contrary to popular opinion
Most updates you get are bugfixes. And most of those bugs you won't even notice. And if you or your family use that system just for emailing and webbrowsing, writing a letter now and then, it won't be such a big deal working with a version of Zorin that's not supported but still works and do the things you want.
Good luck!
