Odd Footer Area Overlapping & Widget Issues

Thank you for this theme! I do have some issues that I really need some help resolving though.

The problems I have are:

1. Ads are not recognizing the sidebar and overlap into the sidebar area. Sometimes my sidebar divider stops showing 1/4 way down my post.

2. Multiple related posts/featured posts sections (I only want one). No option to completely remove these.

3. Text and Images are overlapping each other at the bottom of my website causing it to look jumbled and ugly. They even cover up the title of my website. Not sure what is going on. Please help.

4. I often see that the theme does not recognize when my post is done because there will be a really long blank space after my content and my footer area will be much further down than the end of my content.
