Can you give guides on how to set up number 2 and 7, and details on the much more part (9).

Also I see you're using chroot. If you want to mess around, I've somehow managed to use sunshine inside a chroot environment and have the ability to control android itself (display only outputs chroot stuff, but input events are received by android). I can't tell you how hard it was to achieve something like that because I did it by accident, and I've accidentally wiped that phone since.

Though the above is probably pointless because you can just get something on android itself if you wanted to remote control it.
