You can do it through Appearance > Theme Options
Layout for the 2 column and Styling to change colors and content width.

The default Twenty Fourteen theme can do that, you just need to do a few css style modifications.

You could hide the info by placing the following code into a child theme style.css or using a custom css plug-in.

.author.meta.vcard {
   display: none;
}

#main .format-standard .single-thumbnail a:after {
    content: none;
}

#main .sticky .single-thumbnail a:after {
    content: none;
}

In your admin panel go to Media > Add New

You have to target the site title specifically. Try this code in your child themes style.css.

#site-title {
    font-family: Quattrocento;
}

It looks like you tried to create a child theme and overwrote the parent theme. Could this be the what happened Willard6?

There is plug-in called Fourteen Colors that can do that. Beats fumblin through the css to find the right selectors.
