<address> is by definition of the standard only for contact information of the <article> or <body> it is part of. It's explicitly not a section.
If you want a footer in html5: use <footer>... , it can contain the address element as appropriate.
So I'd go:
<p>The contact email address is shown below. Please use it to make comments and suggestions, or to report broken links.</p>
<img src="mail.gif" alt="email">
<p>Copyright © 2013 John Doe</p>
And do all styling in css. (lucy24 gave you quite a bit useful stuff above).
I'd leave out the id on the address, you're not going to have that many <address> elements in a document.
(esp. since using it for marking up regular addresses is wrong, it's only to contact the "owner"/"creator"/... .
I also left out your static title: add it back using a before if you feel it's important, but honestly: it's not, the look should be sufficient for people to know that's contact info without the explicit label.
