Answer 1

Have you thought of using Ajax to submit the data to the PHP script and use the return value of the PHP script in javascript to plot the data to the map. You can json to send over the data.

Answer 2

Take a look at the Geocoding API: http://code.google.com/apis/maps/documentation/geocoding/. You can invoke the API from PHP with the file_get_contents function:

$url = sprintf("http://maps.google.com/maps/geo?q=%s&output=json&key=%s&ll=%s,%s",
        $query, $api_key, $latitude, $longitude);
$data = json_decode(file_get_contents($url));
