Clean up footer.php? Move "jump to" pulldown to another location?

I'm trying to integrate PunBB into another site. I want to use the same footer I use throughout the site.

PunBB's footer is really complicated. It's full of <div>'s that destroy the flow of my main site CSS. I can't figure out what the hell is going on.

Is there any way to move all the necessary code from footer.php to other files so I can use the footer for just my regular footer?

Put another way: How can I move the "jump to" pulldown menu to another location on the page? I have a left sidebar where it would fit better.

Same goes for the Show recent posts/Show unanswered posts. I don't want these things in the footer.

The footer in my main site is centered. I can't get my regular footer to center within PunBB's footer. Too many <div>s!
