bluebucks adsense theme works good for me.. http://www.hosterio.com/blog/seo-optimized-blue-bucks-adsense-theme-for-wordpress-blog/ Addsense theme is also as good http://www.hosterio.com/blog/addsense-the-google-adsense-wordpress-theme/
From what I have seen the best wordpress themes for adsense are the simple ones. It is to confusing to have a crazy theme and not get the content across to the reader. The purpose of your blog is mostly to get content out to readers who are researching information for themselves or whatever they need it for. So, just go with a basic theme and with good content will come great revenue. I have a simple theme on my blog and it has worked out alright for me so far. Try it out and let me know if this helps.
It's not the theme that makes the click through rates go up. You can do it with any theme. You just have to know why people click on ads.
Any two or three coloum theme can work, in my case i didnt use adds on main page. i use it in the file "single.tpl" so the adds appear with each post when open. it has the greater probability of clicks.
The adsense ready themes are great but I personally prefer higher quality themes that I then add ads to manually.
I decided to throw together a post that is designed to showcase a bunch of Google AdSense optimized WordPress themes that are currently available for anyone to download. Included you will find a screen shot of each theme wphacks.com/best-google-adsense-optimized-wordpress-themes/
