The library online books are available free for everyone as long you're a student. And to my knowledge you can access them off campus, you just have to login with your ARCOM email. So there's no need for a VPN.
And yes, you can watch the recorded lectures at home. That's the whole point of it.
Edit: I wanted to add that it's not difficult at all to use the online books. The only things is they don't have page numbers, so we have to go by chapters and sections. Professors have been very helpful in trying to not only provide page numbers but also chapters and sections for the pre-readings.
