Does clicking on "Default" or "Day/Month and Name" etc. in the Permalink Settings change the URLs on each page and post automatically or I need to do/set it manually for each page and post? Choosing the "Day/Month and Name" option will use the Page or Post Title for the name?
Thank you.
And I guess after doing it will need to update the sitemap too to reflect these changes.

yes
you will need to rebuild site map
do you use a sitemap plugin to make it easier?
