Points 1-4: Unless future episodes say different, I'm presuming the 7 Paragons and Oliver/Spectre are the same characters as before pre-Crisis and everyone else is a new character with similar-if-not-exact-same histories. The kind of history changes that can range from a small costume/clothes change to even a casting character change. For example, there can be different Lexosuits and, if needed, Kevin Conroy can return as Bruce Wayne. Then there's Eobard Thawne...aka confusion that missed out on the multiverse of madness (pun intended). But again, that's just based on less than one hour of Earth Prime's existence, as far as our point of view.

Pre-Post Crisis/Multiverse question: If asked before, I would've done "pre-Crisis"/"post-Crisis" but I could see the reluctance to do so. But personally I'm ok with what's been done so far, which I assume is just putting "Prime" next to each new earth. Like instead of just "Earth-2" it's "Earth-2 Prime"...no mistaking Stargirl's home for Harry and Jesse Wells' home.
 * As far as the multiverse itself, I would think it'd be ok to leave it as one page as I don't believe the Arrowverse will last more than 10-15 years...but I could be wrong, who knows? IF a second multiverse page need be made, I would do what is happening now, like "Multiverse Prime", "Multiverse (Earth Prime)", "Multiverse (Post-Crisis)" or something.

Personal note/rant: For the record, I was mostly ok with Crisis on Infinite Earths as is, though debating on how far does it go in my ranking as the Earth-X crossover was "the better" one. That said, if it's not obvious already, I'm really hoping Kevin Conroy comes back to wash "Evil Batman" out of haters' minds. Just saying, while I personally was ok with how that story went, a lot of people were not...make it up to BTAS fans CW! And while you're at it, get Mark Hamill too!
