Missing firmware is not yet the problem.

As the ERROR message above says, the PHY contained in the BCM4331 is not 
supported by your version of b43. It takes kernel 3.2-rc3+. You can also get 
that version of the driver by installing the latest version of bleeding-edge 
compat-wireless found at http://linuxwireless.org/download/compat-wireless-2.6/. 
You will need to build that code, unless Debian has such a package.

Once you get the correct version of b43, then the firmware and the firmware 
cutter are available at http://wireless.kernel.org/en/users/Drivers/b43.
