No one but you can decide if you need more focus points. In general, you can use just the center focus point to focus on the subject and then recompose the camera to frame the shot as you would like and take the picture. Now the focus and recompose method is NOT recommended if you are shooting portraits wide open because of the shallow DoF. In this case, it is better to frame your shot and choose your focus point (or better yet: manually focus). And, more focus points come in handy when you are trying to continuously track/focus on moving subjects.... say birds taking flight.
Also the 1fps burst mode difference will matter if you are doing high speed photography. like flying birds for example.
If you intend to do landscapes/stills/family/kids, dont even bother.
