If I have a router do I need Airport Express to go wireless?

I'm moving, and will be getting a Comcast modem/router combo for cable and internet. Can my Mac be set up wi-fi without connecting it to an ethernet cable?

    Currently, I have this setup.

    Comcast modem/router combo -> ethernet (could be wireless if you wanted it that way) - > airport express.

    This gives you wireless through the airport express.

    Also, you could just plug the express into a wall on the opposite side of the house and tell it to extend (or join) an existing network.

    Whatever your end goal is.
