You have kernel version 2.6.31, that means you are running Ubuntu 9.10. This version has reached its end of life, so you will get neither security updates nor bugfixes and you will run into troubles when you want to install software on that.
Install a more recent version of Ubuntu.
In the current Ubuntu 11.04 release, you just run the Restricted Drivers app and Activate the Broadcom STA driver. It couldn't be easier (and you don't even need a wired connection).
I found another site with someone that has had a similar problem and they said to go into synaptic package manager, remove bcm-kernal-source package and to install firmware-b43-installer and b43-fwcutter. I removed the bcm-kernal-source package and installed the b43-fwcutter but it won't install firmware-b43-installer. This is a copy and paste from the error box:
Setting up firmware-b43-installer (4.150.10.5-5) ...

No... don't jump around from solution to solution. Pick one solution and follow it through to the end. b43 and STA/wl are two separate drivers that conflict with each other. If your chipset requires STA/wl (as the restricted hardware driver seems to think) then installing b43 will break your wireless. b43 needs to be blacklisted in order for STA/wl to work.
Step 1 is the most important step; properly identify your card using:
Code:
lspci -vvnn | grep 14e4
Why don't you do that and then post back with the result.
To answer your first question, once you've properly installed the correct driver, you need to reboot and then use the Network Manager icon (near the top right of your screen) to make the connection to your wireless network.

Reason: fixed bad link
That tutorial won't work as it's for a different chipset.
For what it's worth, I have the identical chipset to you and have successfully installed dozens of distros including Ubuntu 11.04. I'd recommend checking obvious things like that the wireless is enabled in your BIOS and the card is not physically loose/damaged.
Also be sure to blacklist the b43 driver (and associated ssb module) you erroneously installed with:
