Car has a dead battery, no rearend or rear brake lines, so the car probably shouldn't be started. Anyways, the car will probably not be started for a month or two, will the HPPIII programming last in memory? Or, should I plug the open brake lines and start the car periodically?

Disconnecting the battery will not remove HPP3 programming. It's been written to non-volatile memory and will only change if written over by new programming - including back-to-stock programming.
