I need help making bedwars beds and generators

I want to make beds that when you set your spawn point and it gets broken, and you die it sets you to spectator mode and when the bed gets broken a message appears saying your bed has been destroyed ,and when you die it says final kill if your bed is gone before the death message. I also want to be able to make generators that generate items every set amount of seconds. I need help, thanks.
