How to customize Generate-Pro theme blog posts?

So how do I customize each blog post entry for the Genesis Generate Pro Theme? Specifically I want to:

1) Add a mailing list optin from GetResponse by pasting the following code at the bottom of each blog post:

<script type="text/javascript" src="http://ift.tt/1D4eWDx"></script>

2) Remove the vertical gray/black bar (circled in red in attached pic) that is to the left of each title of each blog post and possibly not display the blog post title as well.
