1 - Yes, wait for mods to get fixed. You should be able to play them natively on the Quest version.
2 - QP? Like, the default "home" environment? If so then yes, go into settings - I forget where but I was there earlier today
3 - The only FPS worth a damn on the Quest store is Onward but it's still shitty. If you Sideload you can play Hyperdash which is really good and has crossplay, so you could join us for the Tuesday lobby if you want. I played from my Quest 2 the other day and preferred it to my Index.
4 - If you have a decent 5Ghz router consider streaming via Virtual desktop. This is assuming you have a good enough PC for PCVR though.
Not sure on 5.
