Thanks. That's the type of info I was looking for.
As for the network, the missing details are that for some reason I cannot access the network drives from my laptop (requires special drivers that don't work on "XP home edition") so I need shared files (which implies same subnet) and then the AirPort is not exactly the most flexible gateway on the market (it cannot act as a bridge). As I have only one port left on the 5-port switch in my living room, only one of the AirPort or the laptop can be cabled.
