Narrative:

While lowering the gear, the 'gear disagreement' light illuminated after the gear was placed down for landing. The 'tail skid' light also illuminated and the gear lights indicated 3 green. We accomplished a go around and executed the appropriate checklists for the indications we had in the cockpit. After the checklists were complete, we declared an emergency and landed the aircraft. On final prior to landing, the ground proximity warning 'gear' sounded, the system was deactivated, and we accomplished a normal landing in accordance with the checklist. Recommend the checklist have a note added to turn the ground proximity warning gear switch off to avoid the nuisance warning prior to landing and reduce distraction in the cockpit.
