Removing header bar and adding more "Featured Content" links.

Hi there. I'm looking to make a few edits to Catch Responsive, and I was wondering if they were simple enough to be taken care of via this forum. I'm looking to completely remove the black bar right below the logo from all pages, and I'm hoping to add a second row of 4 more links in the "featured content" section, allowing for 8 in total. Also, if possible, removing the widget section completely, or just on the home page would be wonderful. Here's an image illustrating what I'm looking to do: https://i.imgur.com/NCiAT2j.jpg Any and all input would be greatly appreciated :)
