Pre-order Google Maps Hacks. Rich Gibson covers overlays in that book, and I believe it's going to be released soon.
http://www.amazon.com/gp/product/0596101619/103-1263761-9439833?v=glance&n=283155 You can get it with Mapping Hacks for $39. I'm completely impartial except for the fact that I wrote two of the hacks in it and Rich pays me to plug his book.
