@jmyss: If you want to use the Featured Post Slider without the title and description then you can upgrade to Catch Box Pro theme where there is Featured Image Slider which gives you control to upload your own image, title, description and links all optional.
For content layout: Catch Box theme has 2 content layout. 1) Show excerpt: which will show the featured image of the post and excerpt text and 2) Show full content: which will show the full content exactly like in the post. You can select the option through Appearance -> Theme Options -> Content layout.
