>where can I find the cheapest quest 2 as of right now?
Check whatever website is the most popular in your country to see if there's any deal in your country, other than that you can go for a refurbished one on Amazon
>How can I connect it wireless with steam?
AirLink, ALVR or VirtualDesktop, VD is not free but a way better option as you don't need to install any oculus shit on your pc and is relatively plug and play compared to alvr
>How much Facebook do I need to have at minimum to be able to use it for steam games only?
Only an account for activation, can remove facebook entirely using oculess but you'll be stuck with alvr
