Hi all
if you are having REAL trouble with the ribbon etc in Office 2007/2010 there's a very nice utility (unfortnately not free but if you are a fan of the 2003 menus probably worth it) then download from here.
It says EXCEL but works for the other office products too.
Classic Excel 2003 Menu replaces Excel 2007 ribbon.
Don't forget in any case you can always kill the ribbon by simply pressing CTRL+F1.
Cheers
