Adsl Problem – What do I need?

I just got an ADSL connection in my home. The problem is, I have to connect two computers and I have a modem/router with Ethernet and USB connections. As these two computers are in separate rooms, I do not want to make holes through 2 rooms to get an ethernet cable to connect one pc and the modem/router.

So my question is, what equipment do I need to connect both pc’s to the ADSL line so that they can work independently (any pc connected at any given time)?
Will two modem/routers make it if I connect them each in the 2 separate rooms?

Sorry for all these questions.
