/vrg/ itself mostly only uses the Japanese DLC on top of mods, I haven't played with them because the games take place after midnight for me, but as far as I know the server is always up, they have a mumble and it's not too complicated a process to set everything up.
Personally I reccomend setting up Content Manager first thing

It saved me a lot of headaches that come with the vanilla launcher. AC's VR support leaves a lot to be desired, but Content Manager does its best to damage control it, as you can set camera reset, race start, restart and so on to wheel/controller buttons so you no longer need to reach the mouse and keyboard to do basic tasks. SteamVR also lets you control the mouse with HMD so in theory it should be possible to control everything in VR, without the need to constantly take it on and off to tweak things on the screen. It also has an option to save presets for races, so for example if you just want to race against a single AE-86 on Akina, you can have a preset for that.
