Yes, the only thing you need is the Lutron dimmer switch.

However, keep in mind that the switch is sold only in a single switch frame, so if you have two switches or paddles in your current installation, you'll need to buy a new frame that allows space for two "paddle switches" and put the Lutron in one of them and the other paddle switch in the second (and third, etc.)
