What is the name for the specific part of the heart which sets the rate at which the heart will beat?
The pacemaker of the heart is known as the sinoatrial (SA) node. It sets the rate at which the heart will beat without any autonomic stimulation, that is, no sympathetic or parasympathetic activity. Increases in sympathetic activity will increase the heart rate while increases in parasympathetic activity decrease heart rate. The pacemaker of the heart is known as the sinoatrial (SA) node.

How can the heart muscle work with no help from you?
The heart muscle actually beats on its' own. It has two pacemakers. One sets the pace and the second, slower one, is a back up. If you had one heart muscle cell (fiber) in a Petri dish it would beat. If you add a few more, they also will beat but not together. Only if they touch, then they will beat together.

Cardiac muscles don't contract in unison, if you listen to your heart beat you should hear two distinctive thumps (1 for the atria, 1 for the ventricles). I believe the structure you're looking for is the Sinoatrial Node (SA node) which is a bundle of nerves in the upper part of the right atrium, also known as the 'pace maker'. The electrical impulse from the node triggers a sequence of electrical events (from the SA Node to the A(trio)V(entricular) node to the Purkinje fibers) which are the cause of the beating/contracting
