You probably just want to set maxres and numZoomLevels on the map,
rather than the layers. The default properties are pulled from the map 
if they don't exist on the layer -- and the ones on the map are the
defaults, because adding a layer doesn't override them, I think. 

So, set the 'options' on the map, not the layers, and you should be all
set.
