Usually on smaller birds you can manage to get a hand in just by cutting the skin on either side up to the ribs. And of course, you can cut all the way up, too if necessary or if you want to. There is actually a small gap between the front and back ribs that if you get your knife in the right spot, it cuts through clean, but I think that would be pretty difficult to do well with the guts still inside, so agree on using the shears.
They sell tools for cleaning lungs, yep. They call them lung scrapers, if you're searching.
Typically with quail people will cut the backbone out, like you'd do when you spatchcock a bird, and then open them up from the back.
I don't see why you couldn't scald and pluck the same as a hard feathered chicken, the feathers must still have quill ends where they attach. Might be a bit harder to get ahold of. Might be a bit easier, too. Hard telling without having done it.
