I know this is an old thread (I'm exploring the other areas of the forum, whoo!) but there is also a program called Steam Mover that works great for this sort of thing. It was most useful before Steam allowed you to create Steam libraries on other drives, but it also works well now to avoid having to re-install to another drive (since Steam doesn't allow you to move the folders without reinstalling)
