Creating forms in Word 2007--any good manuals/online courses?

Part of my job is to create template documents for the reports that our environmental consulting firm puts out. Right now, these templates are rudimentary. I’d like to create one form document that would allow the user to select options from pull-down menus, and to have certain fields mirror each other so we will only have to type in data one time, instead of multiple times in the same document.

Unfortunately, my Word skills are intermediate at best. Can anyone recommend a good manual or course that could teach me how to do this? It would be quite lucrative for me if I could learn these skills ASAP.
