During descent use the auto-pilot (VS mode) to control the rate of descent, and the throttle to control airspeed.
In order to effect the initial speed reduction, the place the throttle in idle. As you deploy the larger flaps levels (15+) the aircraft can slow down quite quickly, and you will have to actively manage the throttle to avoid a dramatic loss of airspeed. Particularly for the full flaps extension it is very difficult to maintain sufficient airspeed to prevent fast descent so deploy these only when you are quite near the runway.
