Twitter/Footer and Previous/Next Posts question

Hi — two questions.
Theme: Thesis

1) Plugin: WP-Twitter Retweet Button

I installed the twitter retweet button, but it’s conflicting with my footnotes. Essentially, the retweet button is going in the top left on the bottom, but if I have a bunch of footnotes, it will look weird. Here’s an example, although on a post with only one footnote it doesn’t look as bad:

But my facebook buttons are below the footnotes. How can I make the retweet button below them, too?

2) On this blog, they have links to the previous post and the next post at the top of the current post, like so: http://www.pro-football-reference.com/blog/?p=9

Is there an easy way for me to do that on my blog? On today’s post, for example, it would be cool to link to yesterday’s post on the top left. Instead it’s just blank: http://www.footballperspective.com/trivia-of-the-day-saturday-june-16/
