yea, alignment is the key : shoulders, knees, feet, hips, and your head determines where the ball goes. Yea, i got that "Leaderbetter Swing Guide" thing where you have a mat with a beam that you connect to the end of your club. And you match the beam with the arch on the mat to get the "inside approach" to help you roll over your hands and develop a draw. My uncle used it more than me cause his natural swing was a strong fade( which i called a slice that he wont admit -_-). But it helped him out more than me, cause my natural ball flight is a slight draw anyway. It just helped me develop better ball control.
