I've added an Adsense add to the top and bottom of the Core style but I can't quite get the CSS correct on the bottom one.

As you can see, it's too far to the right:

Any suggestions on how to fix it?

in the div style="text-align: center;" add in also margin: 0 auto.
One thing to consider too instead of using inline-css i'd just add a class to id, adFooter or something, then in extra.css put your css there.
