If its just the page names you have changed and not the page urls then I see no problem with just uploading. Google will change the page names on the update and your listings will be corrected.

no its the url's

I would upload and then 301 (see thread about moved pages a few rows down) your old pages to point to your new ones. That way when Google et al comes to visit next the new pages will automatically be there.
