Considering change to Wordpress with better theme? What they mean by site navigation is where when the surfer doesn't know where to look for the information that they want.
A good web design will have a consistent navigation panel (a menu, for instance) throughout the site. If you're not willing to do a major revamp, then considering the following changes:
- Clean up the right panel on your blog by reducing the number of gadgets, give priority to the main links to your post (Coffee Tea or Me) by placing them above everything else and change that "Coffee Tea or me" wording to something meaningful (but dull) like "Site Menu" or "Navigator" so that people know those are links to browse through your sites.
- Even though you wanted to highlight the 4 main post by placing it on top but that could mislead people by thinking that that's all post you have. If you wanted to keep them, I suggest you replace them to your right panel, directly below your "Site menu" or give that section a name like "Highlights" or something equivalent.
- Others less relevant stuff: Reduce the size of the banner directly above your page, it only serve as decoration but has little to no space value. Secondly, considering compress the image of your background to reduce the load time.

You can keep a copy of your template as backup then only you apply those changes and try your luck again with Adsense & if nothing work out, you can always switch it back from your back up.
