If she is really interested in playing, like drums, lessons are important to avoid bad habits that will plague you forever. Second, watch women's golf because they hit the ball distances the average golfer can achieve and as a result they have course management skills you'll never see from the men. I encourage all amateur golfers to watch the LPGA over the PGA.
Side note: having worked many tournaments you see on TV, some of the guys are cool, a lot aren't. The LPGA events all had less ego and were generally more fun to work.
