Vista Compatiable?

It's supposed to be able to do that. However, people have been reporting compatibility issues even with Microsoft products. If you find that Office 2003 doesn't work right, Vista has a compatibility mode that is supposed to solve those issues.

Click start > all programs > find Office 2003 in the menu. Right click on the name > properties. In the dialog box put a check mark in the box next to "run in compatibility mode" then from the drop down menu select XP.

In the alternative, you could check out some of the help sites like:

Or contact Microsoft ahead of time to ask them:
