Custom CSS for Page Breaks

I am looking for someone to help create a custom page break and related posts for my wordpress site, www.insidethefilmroom.com. As you can see on a post like this my page breaks and related posts look like crap and my attempt to fix them have failed miserably. Example post: [login to view URL] For the related post it is a simple alteration to a wordpress plugin-- Microkids' Related Posts-- that would allow me to put 3 small thumbnails in a horizontal line underneath post. Currently they are stacked vertically and i cannot figure out how to realign them. Here is link to plugin site: [login to view URL] For the page breaks i am looking for something similar to Bleacher Report or NFLSpinZone. Here are links to 2 pages explaining what i mean [login to view URL] and [login to view URL] . I will attach screenshot that highlight the area i am focusing on as well. The goal is to create a obvious and clear page break with the ability to switch pages with the arrow keys as well as buttons at the top and bottom of every post. I would imagine it would operate off the <!--nextpage--> function. Thanks
