RE: How to slow down plane while landing?
Lifting the nose adds drag when the plane is all ready in some degree of wing stall. It is a balancing act of flying the plane within the parameters of the stall and remaining controls. Many pilots are proficient with a plane to do that and it works quite well to slow a plane during landing. However, I'd suggest that those of us who rotate fly a hanger of several planes will not choose to do it. Adequate familiarity just doesn't exist for the average pilot when flying a plane once or twice a month interrupted by the parameters of a host of other planes. To those good pilots who can.... kudos.
That leaves the need to induce drag by some other means. Slipping induces drag.... no? As do flapperons, flaps, flaps and spoilerons (crow), shallower glide slope and my favorite a longer prop with a smaller pitch.
