Question : My option and command keys are switched on my mac

I have an iMac and I had a windows Logitech Keyboard installed on it (This computer is a work computer, and the keyboard and its drivers where installed before I got here.) Anyway, the keyboard is extremely noisy, so I got a wireless apple keyboard. Now when I use the apple keyboard, the command and option keys are switched.

I have tried to go into system preference, and under keyboard restore the modifier keys to default, but nothing changes. There are two users on this computer. Do I need to also switch the modifiers on the other user?

Do I need to uninstall the Logitech keyboard? If so, how do I go about doing this.

Thank you for any input.

Here is information on deleting your Logitech Software:  http://forums.logitech.com/t5/Mice-With-Mac/Logitech-Control-Center-2-6-Release-Notes/m-p/223280

After doing so, zap the PRAM again.
