The router will auto configure the connection and both PC's will be able to use the net at the same time. If you get stuck the manual takes you through it step by step.
My setup is exactly the same. I have a 25 metre cable running from my bedroom to the back room downstairs to connect me in. Both the parents PC and mine can access the net at the same time.
