I can’t really help you with your problem (even though I think it might have something to do with the ads and you should look into that) but I’m gonna tell you that Google doesn’t like the “Click to support” thing, just label it “Sponsors”. Trust me.
But, as I said, try and tweak the ad box you used, it looks like it’s frakking things up on a single page.
I can add those two to the list:
WP-ContactForm
Secure and Accessible PHP Contact Form
Never got the to the settings page with those enabled.
