Question

Answer 1

You could try some of the js extensions available online. For example: http://code.google.com/p/earth-api-utility-library/source/browse/trunk/extensions/examples/ruler.html?r=41

Answer 2

I'm not familiar with the Google Maps API, but given latitude and longitude of any two points you can use a great circle calculation to determine the distance between them.
