Good that you still made it.
Here’s a fresh tutorial that may be of use for you:
Even though some of what you listed could be used currently I do not recommend trying it now. It’s not user friendly to set up (no ingame input configuration) and it takes quite some time. Rather use that time to enjoy the game with the default mappings for now.
Player cameras? I don’t exactly understand what you mean but you are free to show the game arround as much as you wish as long as you point out that it’s still in pre-alpha and most stuff is still placeholder.
