Indeed that is a good way of getting airborne again! The main purpose of lifting the nose wheel is to keep the load off the nose wheel, the reduction of speed is secondary.
As mentioned before you shouldn't be bothered with the rate of descent. When you turn finals you should be concerned with your position relative to the runway i.e. the picture out the window, and your airspeed. Dont try to aspire to figures and numbers (except airspeed!) on finals. Try to fly a stabilised approach that will give you a healthy airspeed and keep your aiming point static in your window
