This seems to work for one kml file:
google.maps.event.addListener(ctaLayer, "metadata_changed" ,
function() {
map.fitBounds(ctaLayer.getDefaultViewport());
});
Since you haven't provided a link to your map, I don't know if it will
work for your code structure and I don't know that the
"metadata_changed" event is the best way to tell that the kmllayer has
loaded, I don't see a complete list of the available events in the
documentation. Maybe one of the google engineers can shed some light
on where those would be documented.

I believe the initial zoom is needed to "initialize" the map.
Although the documentation isn't very clear about what is required to
initialize the map.
