Yes, this would bee needed. You can reuse your original if they are not damaged.
The strut boot keeps your struts protected from dirt, dust, sand, salt and other road debris. It's designed to protect the strut from bottoming out and protects other components from extreme movement damage. The purpose of the bumper is to limit suspension travel by not allowing suspension components to hit together.
