Answer 1

The best way to centre an element is using margin: 0 auto;, try changing your code to:

#main {
  width: 680px;
  margin: 0 auto;
  padding: 0 40px 5px 40px;
  font: normal 14px Verdana, Arial, sans-serif;
  line-height: 20px;
  z-index: 2;
  background: url(images/content_back.png) repeat-y;
}

Margin: 0 auto sets an "automatic" margin for the right and left, essentially centering it. (This only works if you specify a set width, which you have)
