Happy to offer assistance if you want. I’m running bazzite with steam as well as lutris for wow. Using lutris for tradeskillmaster as well, and wowup-cf for mods

Grip tape? There’s a ton online you could order, or hit up your local hardware store. May kinds are designed for outdoor ramp/stair use.

I also had issues trying to successfully set up vnc, specifically trying to connect from a Windows pc to the Linux box.

I would recommend trying rustdesk instead if it has the features you are looking for.
