Answer 1

According to Google you can just avoid highways, ferries and tolls. You can also choose the mode, but not 'fast roads'.
For example:

http://maps.googleapis.com/maps/api/directions/json?origin=Toronto&destination=Montreal&sensor=false&key=API_KEY&avoid=highways&mode=driving

For your application you can do this:

String url = "http://maps.googleapis.com/maps/api/directions/xml?origin=Toronto&destination=Montreal&sensor=false&key=API_KEY&avoid=highways&mode=driving";
HttpGet httpGet = new HttpGet(url);
HttpClient httpClient = new DefaultHttpClient();
HttpResponse httpResponse;
try {
    httpResponse = httpClient.execute(httpGet);
    HttpEntity httpEntity = httpResponse.getEntity();
    InputStream inputStream = httpEntity.getContent();

    DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
    Document doc = builder.parse(inputStream);
    //In doc is your response
} catch (Exception e) {
    e.printStackTrace();
}
