That error almost always indicates that you lack the appropriate line for the device in /etc/network/interfaces. Are you certain that your eth0 line hasn't been changed or commented out?
So long as the line is there, even if you do not have the correct kernel module for your card loaded, you usually will not get that error. You would get something like "No such device", or "Bind socket to interface: No such device".

Does the configuration displayed by the intervening "ifconfig" have the correct parameters for your wireless network?
But that's another issue. You should determine what is wrong with your (PCI?) ethernet card first, as that is more likely a much simpler issue.
