Promotion Headline Font Size, Padding, and Button Location

I would like to change the size of the Promotion Headline Text and Promotion Subheadline Text? How do I do this? Also, I would like to reduce the padding of the Promotion Headling so that it's a little tighter. Lastly, I would like the button to be located on the far left side with the headline just to the right of it with left justified text. How do I do this? URL is http://4xq.ca2.myftpupload.com/
