Way too much green. Also seems a little confusing where the ads start and the content begins. Work on a stronger color scheme and think about your text hierarchy. Right now everything blends in together and I'm not sure where I should go first.
I don't think thats the right attitude. I didn't click anything because I didn't know what I was supposed to click on. If you want the ads to be successful, make them look integrated, yet distinct. Don't insult your visitors by hiding your content amongst outside links.
I think the shadow is too heavy. The ads are very nicely intergrated. But you have empty space on the upper right. There is not contrast between any areas. I would customize the colors on the free proxy script to create contrast with the page background.
Hope this helps. You need a color scheme, don't really hate or love the green, its just 1 color, no real design to look at.
