The simplest way to restore the default settings is to delete the configuration file. But if you delete individual options in the file, the defaults for those options will be used. For what you want, I suggest deleting the "Reading" and "PowerOptions" sections.
The only problem with the above is that the reading settings can be stored for a book. If you adjust them while reading a book they are stored for the book in the database. So, for existing books, you need to remove them. My Kobo Utilities plugin has an option to do this.
