Broadband equipment suggestions

My father and myself have both go broadband recently, but did not get any routers from the supplier, and are sick of waiting. We have decided to get our own and I am looking for recommendations on what types to get.

I have only one PC, and will be playing games, so was thinking along the lines of just using a cable setup, and my father has a PC and laptop and wants to go wireless
My father go a "US robotics wireless turbo access point and router model 8054" does he need an adsl modem too, or is this enough?

Also, because i am thinking of going down the cable lines of things,
Is using USB faster than the ethernet way or is it the other way round?

Thanks for your help in advance
