Insulate the common wall only. Use fire rated drywall (or double up on regular stuff, I think?), as was mentioned, if you really want to do it and feel a difference, get the expanding foam stuff shot into the stud cavities while the walls are open.

Insulating all the outer walls won't net as much benefit because the garage door is still the huge source of cold air and is not heated. Plus everytime the garage door opens your are back to square one.

Take the money you would spend on the other three walls and use it to get the common wall insualted with the expanding foam stuff. No more drafts, leaks and you'll definitely notice a difference. And its a good noise insulator as well in case you need to pull an all-nighter working on something.
