Hi, I cannot answer all your questions however heres what little I can help with!
Before breeding you want a good nest box..with moss or something inside that your female can dig to burry her eggs
By ratio, do U mean how many females to 1 male? If so some people keep 5 or more females with 1 male!
Before breeding just make sure that your female is looking heathy and try to give her as much calcium as poss prior to breeding, to help her through.
As for your incubator this is a link that may help

I hope this helps a little till someone with more usefull knowledge comes along!
