Pilot's checklists are for reminding the pilot to configure the aircraft properly for landing. You know, wheels, flaps, speed brake, lights, etc. Piloting the aircraft is what you can do well with practice, practice and more practice.
Films I have seen of Harrier landings bring the aircraft to a hover over the water near the ship's deck and about the same height as the carrier tower. This is to make sure you can get into a hover without wrecking the carrier in case there is some unknown engine or nozzle problem. Once stabilized, the pilot slowly moves over the deck and sets the bird down.
