howdy from a little ways up the coast lol.

for the crack, i think i would just put a backing piece epoxied to the back. im not shure if you couldnt make a joint and stick on a new piece of leading edge there, but ill leave that to the guys who have fixed that issue before.

check you hinges very well. i had the elevator pull out and destroy my airframe(i got mine about the same way you got yours....) just a few days ago
