You did not mention the steering column. It needs to be removed FIRST. And do not think you can remove the column from the steering box. You need to remove the steering wheel, and column shifter if you have one, and unbolt the box from the frame rail and then remove the box and column as a unit.
But if you remove everything from the cab, it is not all that heavy. But if you decide to leave things such as glass, better get 3 buddies.
