First, most of the things you mention will come with experience. Be patient.

When I land, I fly a regular pattern. Downwind leg parallel to the runway, base led at 90 degrees, then the final. Do it the same way every time, unless you have an emergency.

Get a more experienced pilot to fly landings and you follow him. Use similar planes. He will be in the right place, and it will teach you how your plane looks when it's right. Don't fly in relationship to the background. If you go to a different field, you'll be in trouble. Fly the plane.

When you turn base, fly the plane towards yourself. If you're standing within 20' of the runway, you'll be close to being right over it at the threshold.

Practice fake landings until you can get parallel. Just make landing patterns with a low flyby.

Hope this helps.
