I cant remember on '80 but pretty sure you have a door striker. If so you need to look for later style CJ doors. And as already stated YJ doors are a good option. Craiglist will be your best bet without having to worry about shipping but eBay is another option. There are good deals to be found, just less of them.
As far as your rear hatch you will probably pay 60%+ the cost of a used top for just the hatch....if you could find one. I sold my hard top last year for $350 which is middle of the road on price. But you may get lucky.
It's red too.
