With Headers/Footers you get easy Page Numbers. With your document in Print Layout view (default), double click at the top of the page to access the header. Do the same at the bottom of the page to access the footer. Look up in the right-hand section of the Ribbon and notice that you now have the Header & Footer Tools contextual tab called Design. On the left of that Ribbon, you’ll see the Page Number button in the Header & Footer group. With your cursor positioned exactly where you want the page number, click this button, choose Current Position and the style of page number you’d like. Voila! All of your pages are now numbered.
With Heading Styles you get a Table of Contents. Using simple Heading 1, Heading 2 and Heading 3 styles, you can generate a Table of Contents in a couple of clicks. First, select each piece of text that you wish to be the highest level heading and press Ctrl+Alt+1 or click the Heading 1 style choice from the Styles gallery on the Home tab. Do the same for your second level headings, Ctrl+Alt+2 or Heading 2, and if you need to, Ctrl+Alt+3 or Heading 3. With all of your heading styles in place, insert a blank page where you’d like to place your table of contents. Position your cursor at the top. On the References tab, click the Table of Contents button in the Table of Contents group, then Insert Table of Contents. You can choose how many heading levels you would like to include in your table. Then, click OK. That’s all there is to it!
