@adongol: I am not sure what do you mean by Heading text. Do you mean the title of the page and post. There in easy to use Font Family Options and color Options in Catch Everest Pro theme. But for free theme, you need to add CSS in “Appearance => Theme Options => Custom CSS” and adjust it.
When you add css, make sure it is compatible with the Mobile devices, especially the font size.
.entry-header .entry-title { font-family: sans-serif,Arial; font-size: 30px; color: #222; }
How can I remove the comments section of the page?
— You can remove comments section of the page from “Edit Page” discussion box. There you have to uncheck Allow Comment. See this http://en.support.wordpress.com/enable-disable-comments/
Is it possible to remove the white arrows on the featured image on the front page (I only have one image)
— You can just add the following CSS in “Appearance => Theme Options => Custom CSS” box.
#slider-nav { display: none; }
.
