1) Do USB pipes toggle between one and another on their own? If not,

Eaxh pipe/endpoint has its own data toggle. The rules of data toggles are layed out in the USB standard in chapter 8.


2) What needs to be done to make them toggle,

The rules say that an endpoint should only toggle its toggle when a transaction is successfully completed. That's transmission of an ACK for the receiver and receipt of an ACK for the sender.
