There is no setup guide in such detail, sorry. I will try to help with the ones that you've listed as an example.
Top header is the bar above the logo and navigation, "Dark" means near white fonts on near black background, and "Light" is the opposite of that. These colors can be aditionally customized under Style > Header Top section.
Hero width is based on the website width, there is no setting for this, you would need to customize the CSS styles.
