Help me understand something... doesn't hydraboost utilize the hydraulic pressure from the power steering pump to "boost" the brake pedal? Is there actually an accumulator somewhere that holds some pressure to aid in braking once the engine is off?

Yes, and yes--it holds some pressure both in case of the engine shutting off and in case of the power steering pump or its drive belt failing. The accumulator is sometimes incorporated as a part of the hydroboost brake booster unit itself, rather than being a physically separate component. It only provides emergency pressure for the brakes, not for the steering power assist.
Here's
some more general information, perhaps more than you really wanted, on the system.
