I have a couple of hints for you:
1) at your level the ball position should not change much, assuming you are right handed, the ball at address should be positioned directly under the logo on your left chest. Only exception might be for a driver
2) proper alignment is critical, lay down a directional aid to help, improper alignment creates the need to make corrections during the swing
3) a decent (read not perfect) grip is important, otherwise once again corrections need to be made during the swing
4) once you have decent (read perfect is not needed) grip, alignment and ball position, ALL you need to remember is to turn back and turn through to the finish with 85-90% of you weight on your left (once again assuming you are right handed) foot. At the finish your right knee should be touching your left knee.
The above information is all you need until you hit single digit handicap numbers. Trust me, the game is simple
