Crashem gave you some great advise and was right on. I'll add a little to what he said.

Altitude is controlled by throttle and pitch is controlled by elevator. I think you're right and answered your own questions with both your answers. Again, every plane is a bit different, but the principal remains basically the same.

Reduced your throttle on final or before your turn into final (depending on the plane) and it should begin to lose altitude. You generally want to keep the nose of the plane level, if not, close to level. As the plane is about to touch down a foot or so above the surface, slowly begin to feed in some (up) elevator as to flare. You said the plane is bouncing when touching down? That's a case of probably coming in too hot or losing too much altitude too fast. You might want to stretch that glide path a little slowing the plane down more, allowing you to grease the landing, but us caution as the plane can stall

It all boils down to practice, practice. Experiment a little with different glide paths, angle of attacks, etc. You'll get better as you get more flying time.

Good luck,
