Well, the purpose of the plunger is to sort of help guide the arrow to the target, especially when used in conjunction with a good arrow rest. This occurs by aligning the nodes properly so that the the arrow's path follows the nodal plane correctly.

The reason for using the plunger is that the arrow bends quite dramatically when released with fingers. A plunger acts to counter or correct some of this bending to keep the nodal plane in line to the target. It also helps to facilitate good clearance when set up properly with a correctly spined arrow.

A good demonstration of this can be seen in this Beiter video

More about this can be understood by reading the Easton tuning guide.

If you are just learning the basics, I would recommend a medium spring tension set at the initial position so that the arrow point is just to the left of the string (for right handed archers), as illustrated in the above link.

Also make sure you have a decent brace height setting that fits within the initial range recommended for your bow's length.

From there don't mess with it too much, you should focus more of your energy on executing a good shot.

As you improve, you may want to spend a little more time fine tuning your equipment, but at this point you'll want to fine tune yourself before you start tweaking the equipment. Otherwise, it will be difficult for you to understand what improvements you have made, and what areas you need to focus more on.

I hope this was of some help.
