@Styracosaurus Rider When those ads were first enabled on my wiki, it overlapped the content too. When I started using mainpage column tags instead of a full-width table, it automatically scrolled down the right amount. When I was trying to figure out what I could do, I found that it always had the same width (around 670px) but a different height, which is why it was important that I used the column tags instead of setting the right cell's padding-top to 400px or however high it usually was. It looks to me like your wiki could easily be ported to these tags, since you're already using a column format anyway. Just put the top banner and slider thing in the left column tag and move everything out of that tabe and into the tags, and it should look perfect.
