For the first one, you need to check for the options available in your theme to use full width. Or I could provide you the custom css to do so.

 .content-box>.container>.row>.col-md-8{
         width: 100%;
}

I would refer you to use this article to add custom css:-

For the second one, you can do it through:-
https://www.wpbeginner.com/plugins/how-to-hide-post-and-page-titles-in-wordpress-single-pages/
Or, you can do it through custom css too:-

span.dojodigital_toggle_title{
     display: none;
}

any suggestions on how to lock it top left and right?

thanks again
