Yeah, it's an all in one, you don't need to download anything else except the cfg to get your load order sorted.

There is a native linux build of TES3MP. Just point it to the Data folder included in the all in one and you are good to go if you are OK with playing flat. Otherwise use wine to play in VR.

Yeah. It just werks with Oculus and Index controllers. I think that Vive Cosmos players are fucked though unless they make a custom binding. 

The server is again always up, so you can test things ahead of time and set up your character. Or be creative and horribly grief everything by killing all of the NPCs in the game before 8PM EST, your choice.
