Twenty Ten: change padding between end of article and tags, categories etc.

I’m using the TwentyTen theme.

How can I change the width between the end of the article, and where the categories, tags etc. are displayed.

My site is http://www.devilsofmanchester.com and I’m basically trying to reduce the space between the “Read More” button and the text below it because it looks ugly.

I think the problem is something to do with padding.

Thanks.
