The file:

does much of what you are looking for. The WMS overlay is just for
demonstration.
The only reason to use tiles is for smooth panning but Google does not
like you clipping off the logo on partially hidden tiles. Fetching a
complete map is faster than stitching one together with tiles. Unless
you are panning a small distance which can be done by repositioning
tiles already loaded, you gain nothing by using tiles. OK, a small
caching advantage may exist. Tiles are essential for animation but
the API makes it impractical to do flight simulation.
