What exactly is "nesting"?

If you have some parts to cut out of a piece of metal/plastic/wood etc, you'd want to arrange the parts to use as little material as possible. This is a common problem if you use a laser cutter, plasma cutter, or CNC machine.

In computer terms this is called the irregular bin-packing problem

How much does it cost?

It's free and open source. The code and implementation details are on Github

Curious if you have ever thought of doing a pencil sketch first and deciding the best way to place your objects before jumping into Illustrator?

I mean I sketch quite often with pencil and then ink..... then I bring it into Illustrator.  Sometimes I might make some changes in the digital stage.  But at least I have a kind of a game plan so to speak before getting bogged down into the Graphic side.

Something to consider.
