1. Why are you trying to do things in reverse? Conventional wisdom is
that custom layers go above the Google layers.
2. There is a gray background that is set by the api to the container
DIV. Is that what you're thinking of?
You can change that background, after you setCenter(), with
document.getElementById('map_canvas').style.background = '#ffffff';
replacing 'map_canvas' for the correct ID of your DIV.
3. Here's a heatmap that looks perfectly normal to me, and you can
adjust the opacity of either layer:
