I have a button that when pressed I want it to remove the second
polyline that gets drawn on the page.

Basically, I need help understanding how to keep track of the polyline
ID - once I can do this, then I could more easily create a function
that tells it to change the color of line X to color Y etc.

I would also like to know where exactly the lat/long values get stored
for the polyline?

My project thus far is below.  Thanks for the help.
