I'm not sure whether this applies, but if you are on the LinkedIn website, I recommend you look into the offer of your first month of LinkedIn Learning (formerly Lynda.com) for free. I think you have to use a card to secure future payment, but there is plenty you can do within a month. When I changed jobs, and went from an Excel-heavy workload to long documents with long appendices, I needed a refresher in some of the Word features. Any course on there taught by Gini von Courter, I recommend. Her instructions were really clear.

I did Word 2010 Essential Training, Word 2010: Tips, Tricks and Shortcuts, a class focusing on Styles (I should have done this second!), one on Forms, and one on Creating Long Documents, which made me realize how poorly our long documents were being done. We had 2010 at the time and have since changed to Office 365. I can't remember whether there were 2007-based classes, but it's worth a check. It's the best free training I could readily find. There are also more topic-focused videos on YouTube which can be helpful for picking up specific functions.

In the short term, as Italophile said, change the page break between TOC and your first page of your document you want page numbers to start on, to a Section Break (found on the Layout tab of the Ribbon) and then you can start a new header/footer. You could, for example, have any foreword and your table of contents be numbered ii and iii before starting with 1 through 10 in your main section.

Best of luck,
