Whilst it's true many programs that run fine on XP won't necessarily run on Vista unless the program's developers have recently updated it and expressly state that it does run on Vista, your Office 2007 applications should all work just fine despite what you've been told. Office 2007 is, after all, the latest current version, and no way would Microsoft release Vista unable to run it. That would be extremely counter-productive in their efforts to sell either of them.
Any version of Office from 2003 onwards will run on Vista I've been told by a PC World business advisor. And from personal experience I can tell you that even Office 2000 will run on Vista except for Outlook 2000 which just wouldn't play nicely.
As for your other applications, they might run, they might not. Trying them is the only surefire way of knowing and not just relying on "what someone told you", but Office 2007 should be fine.
Also, be wary of people telling you which applications won't run on Vista, especially if they sell software themselves!
Or, they might simply be repeating what they've heard elsewhere and just assumed it must be true.
