There are many web sites with tutorials, and you might one or two of them worth doing. Most are probably for Excel, so you might want to think carefully about whether you'd want to do one of those.

For a book, you might try something like 'The Secret Life of Word: A Professional Writer's Guide to Microsoft Word Automation' by R Delwood. This isn't a programming book, and doesn't profess to teach you how to program. Rather, it shows how to combine Word's various tools to achieve whatever the desired result might be. The only reason I can suggest this book is that I did much of the technical review; I'm sure there are plenty of others out there. Another that I contributed to is 'Word Hacks', by A Savikas, but that one pre-dates Office 2007.
