Office 2007: backwards compat collateral

As part of the Office 2007/MOSS project I am working on, my customer needed some information around how to deal with backwards compatibility and Excel/Access macros as part of their rollout. These are all common areas of concern for any Office upgrade - below are the URL's with definitive guidance in this space. The migration planning manager is of particular note - this is saving me a ton of time right now whereas previously a lot of manual testing would have been needed.
