How to change block color and font for header

I am trying to migrate my site from .com to org. and have just about everything but the fonts and colors. I am using the parament theme and I would like to know how to change the color of the block where it says Posted by ….
Also, I would like to know how to change the fonts for the title/header of the posts. (on the .com the 3 fonts are Raleway, “calluna sans”, Ubuntu)

To give you all a better example of what I am talking about.. The site that I am trying to duplicate exactly is http://badsentinel.com (wordpress.com site customized using pro bundle.)

the test site I am working on is http://pacontreras.com

here is the code from my style.css

[CSS moderated. A link to your site is all that is needed]

Any help would be appreciated.. Thank You very much.
