I need some guidance

So trying to figure out what I should do to play fallout 4 VR . Do I have to download the base game then the VR version too? If so which one of these two . And in those two do they have some mods that come with them ( I heard I need something called wabbajack) so if I need that will there be any problems in terms of compatibility since one group of mods would be in vortex while others will be in the game files ( since they came installed with the files...??) right..??? Am a little bit lost
