I'm working with Excel 2010 and it's tabs, so hopefully 2007 has same options in roughly the same locations. (It does, I just checked on another system here with 2007 on it).
Right-click on any worksheet's name tab and choose "Select All Sheets" in the list that appears. Then go to the Page Layout tab on the Ribbon and open up the Page Setup group. Choose the [Headers and Footers] tab and set up your custom header/footer. It will appear on all sheets selected.
When you are done, click on any single sheet's name tab to ungroup them because if you don't then anything you enter into the visible sheet will also affect all other selected sheets.
