Narrative:

During approach for landing at cle, the nose gear did not indicate down and locked when the gear handle was lowered. We cycled the gear, and this time all 3 green lights came on. At approximately 250-200 ft AGL the GPWS gave us a 'terrain' warning, so we went around thinking there might still be a problem with the gear. On the downwind leg, tower offered to have the emergency equipment standby, and I accepted -- not knowing if the nose gear would lock down again. But it did, and we made a normal landing. Supplemental information from acn 281491: it was learned the following day, that the nose gear actuation was changed by maintenance.
