Regards,

You may want to check the documentation first.

map.setCenter(new GLatLng(37.4419, -122.1419), 13);

The second parameter should be the zoom level.

I thinks it's not such weird question, assuming he read the documentation, and knows he can set the zoomlevel in a ratio. This ratio is a kind of weird choice... it depends on the initial chosen bounds, and not very intuitive in that matter.

Here lies maybe the answer, you could define 2 points around the point you want to show, one northwest of the point (distance 12,5 km.) and 1 point southwest (also 12,5 km disctance). Than create bounds with this points and zoom to this bound.

A lot of coding, but it can be done.

So you should consider whether you want this, or just choose a proper inital zoomlevel.... (in ratio, not in km)
