Something like this. Please note that this is just to guide you to the right direction. You have to stick in there youself the equal height columns by using any technique and also the sticky footer.

EDIT 1
Try this. This works perfect. The Footer sticks to the bottom even when there is not enough content and pushed down when there is more content. Also the verticaly Scroolbar does not appear. Now please don't ask me to make the columns equal height as well.
