Nitrate is uncomfortable at high levels, but not usually lethal. Ammonia/ammonium is lethal, and nitrite can be even more toxic in hard waters.
If the ammonia is high (anything over 0 is high. .25 is damaging to fish gills, and lethal to many invertebrates) you need to get that fixed before the female will have a successful brood. Since ghost shrimp is a catch-all term for many clear shrimp, you may or may not have a freshwater breeding species. Some people cannot breed their ghost shrimp because some of the species that fall in that category need brackish water for the shrimp to survive.
If you have a freshwater breeding female and a freshwater breeding male, the next time the female sheds her skin she'll bring out her eggs and the male will fertilize. But if the ammonia is over 0, the larva will generally not survive.
Breeding freshwater ghost shrimp is really easy, just have clean water and food and they'll go at it, no work involved for you. At this point, if you want to breed, you'll need to figure out why your ammonia is over 0, and fix it, then they'll begin breeding usually.
