I'd test a large block (336x280 for example) in between post title and start of content. For the Adsense links, I'd alternate between the green you use in the post title, and the blue you use in the navigation links on the left.
I second cri8bat. Place a square block in the middle of the content. I like your blog otherwise Cheers!
It is really nice, clean design and good typography. I like it very much. Logo is fine but maybe you could change typography on the "helping you save your home now".
