The best advice I heard for learning how to land was simply, don't!
When you round out the plane will try to land itself but try to think of it, as your job being to try to keep it flying as long as possible. That's why you're flaring, to try and keep it in the air, all the while losing airspeed until you finally stall just as the wheels touch the ground (that's the theory anyway!).
Just keep practicing and soon it will be second nature (well, easier).
Re thinking you've got it nailed, then taking two steps backward - that's flying matey!
