1) I have not seen any recent official statement pertaining to the need to flash new firmware for the keyboard, try it and see, I guess.
If it works good, then all is well. If you have problems, THEN reflash as per the instructions.
2) just download an OS from the wiki, then flash it to an sd card ( I use Balena Etcher ) then that should boot automatically when the card is
in the sd card slot, from a fresh boot up.
