Make the main pages in the file 1.0 priority. Index, About, Contact etc and any pages that are regularly updated.
Make any sub pages 0.8 and pages like FAQ's and Privacy as 0.5
The easiest way if you have hundreds of pages is to use the search term of '1.0' in your web editor and replace them with 0.8 or 0.5 and then do the ones that need to be seen as 1.0 by hand.
Re-submit once all done.
