cmalott, if you just opened Safari, the Back/Forward buttons will be grayed out since you just opened the homepage and there is yet no previous page to go to and no next page to go to. The Back/Forward buttons should activate after you go to a different page. If that is not what is the problem, when Safari is open, from the View menu choose "Customize Address Bar..." Then, click and drag the "old" Back/Forward buttons off the Address Bar and they should go poof in a cloud of smoke. Then click and drag a new Back/Forward button from the Customize options to the Safari Address Bar. Click Done. See if the buttons work after you navigate to new pages.
