How do Bostrom type simulation arguments normally handle nested simulations? If our world spins off simulation A and B, and B spins off C and D, then how do we assign the probabilities of finding ourselves in each of those? Also troubling to me is what happens if you have a world that simulates itself, or simulations A and B that simulate each other. Is there a good way to think about this?

A world simulating itself would be highly unlikely. It's theoretically possible to have a universe simulate itself, since it can do things like just read from records instead of simulating the computer itself, but it's not really feasible. You have to simulate a smaller or more coarse-grained universe than the one you're in.
