If you mean Word's Styles tools, I use them all the time.

Kat, may I suggest you change your Page Setup in Word to show the final page-size, then go through and remove the forced page breaks, if any, and then work your way from front to back with the end results showing in Print Preview or n Page Layout View and re-insert page breaks as appropriate. This will bring you to the end of the document with the breaks all in the right places. THEN check for spelling, or typos, and print to PDF.

If your version of Word doesn't print to PDF directly, then use "print to file" to produce a Post Script file and then use acrobat Distiller to turn it into PDF.
