Well personally, I think your site is excessive on the advertising. I mean it's not even well thought out advertising. The first AdSense code should be a banner width and height.
Then you have all of those what I'm assuming are affiliate banners going down your entire navigation bar.
Lastly, you have those "now just in" boxes. They are adding size to your size. It should be on the bottom of the page, if at all. Your goal should be to keep users on your size is it not?
So pretty much, I'm going with the fact that if you want to get your site off the ground, you're probably going to need to reduce the advertising on a huge scale.
Instead of making all those large affiliate banners, why not make your navigation bar look a bit neated. Decrease the size of the link fonts in the navigation bar, and make more links instead of having one main topic with about 15 choices from there. The easier the user can find what they are looking for, the better you'll do in educating them and keeping them coming back.
Hopefully you see that I'm trying to help you
