You'll prob also need to change MTU to 1500 or at least 1492. In fact I'm surprised that it's set to 1400 for BT. Sure that will be slowing you down by unnecessary fragmentation of packets.
Whenever you see a Username/Password combination in a router's set up it will always be those for logging you into your ISP, however they are phrased. It could be that BT doesn't use them and just authenticates you by your phone line no.; any BT user here would know.
Watch out for these hints:
WAN (Wide Area Network) pertains to the outside world & the Internet.
LAN (Local Area Network) pertains your own local network of devices.
