How can I format footer sidebar in twenty fourteen so they are aligned with the page content?

Hi - I am using twenty fourteen and have multiple footers. My site is at http://www.studentconnect.co.uk/wordpress. I would like these footers to be closer to the content - they pear too far down the page. I would also like to indent where the footers begin and end from the left and right of the page, to centre the footers under the content.

Finally, I am using meta-slide for images on the home page, and would like to have a drop shadow underneath the image slider. Is this possible? I have seen it on some other themes.
