Answer 1

Just to bring this up to date... they've made it very easy to do on Google Maps API v2.

    mMap.addCircle(new CircleOptions()
        .center(center)
        .radius(radius)
        .strokeWidth(0f)
        .fillColor(0x550000FF));

Where radius is in meters.

As for markers on the boundary, that should be relatively easy to do - just follow the 'Circles' Demo in the Google Maps sample code here: https://developers.google.com/maps/documentation/android/intro#sample_code
