Narrative:
During VFR approach I was PF. At 1000 ft AGL on ILS runway 1R on GS; noticed gear was still up and flaps 2 degrees. I called for landing gear down and flaps 3 degrees and disconnected autoplt. Almost immediately we hear 'too low terrain' 2 times. Called go around and informed tower. During go around; calling for flaps 2 degrees; I allowed the aircraft to overspd the flaps. Missed approach and ensuing approach/landing. No further incidents occurred. Reported overspd to maintenance.
