I am using Firefox 3.0.3 on Windows XP, so maybe the float issue is specific to that for some reason?

Look below where I would submit a comment, and you'll see both the previous and the next post links right next to each other.
As far as turning the 'knowing nothing' into a link, what I do is something like this...
<a href="whatever" id="foo"><span>Whatever</span></a>
Then in your CSS, put something like...
#foo { position: absolute; height: 100px; width: 100px; left: 200px; top: 200px; background: url(sfaf) top left no-repeat;
}
#foo span { position: absolute; height: 0; width: 0; overflow: hidden; }
It's a little trick to make an empty anchor that you can style however you'd like. Could even put that in your h1 and make sure the link matches the title.
I would do that for your main page links also... You can see this technique applied at the footer of my Section 508 website at http://www.wp508.com for a working example.
