If I want to display the featured image on a post, but have them appear right aligned on a single post what settings do I need to change?

If you want to align images on the right side and Excerpt on the left side you can add this to Theme Options – Other – Custom CSS.

.medium-wrap .post-featured-image {
	float: right;
