I'd say, 1 static, 2 not unless drawlenght over 24" as I would do it. and 3 no he handle does not have to bend if you don't want it to. I would shoot for 50#@24" with a non bending handle and static recurves when the handle being 4.8 inches (12 cm) long.
oh and if you decide to back it, don't back it with sinew. in my opinion the bow is too long for that witch leads to an overweight bow. and that will make the bow slower..
