Hi loretta,
Thanks for posting your questions regarding the customizations you would like to make on your website.
I’m not quite sure what you mean by making your Homepage more narrow and easier to navigate with separate sections. You can modify the Home page using the Page Editor.
I’m not quite sure what you mean by how you want to customize your blog page. Can you please elaborate?
If you want to create a link for Facebook on your website, you can do this in a Widget or by creating a Menu.
I hope this helps.
Sincerely,
Carlos D
