Change order of items below a post

I am new to WordPress and I currently have the Related Posts plugin, Share This, and other plugins on my site. I don’t like the order they show up though. I would like to move the related posts below the comment box.

Is there a plug in or some other way I can change the order of these things?

Here’s a link to one of my posts. http://lukejc1.com/everything-else/140-characters-or-more/
