I would look at Panda changes as permanent changes. The Google algo has been evolving for years and that is not going to stop. The old ways to rank a website are now obsolete.
I do not think that Panda penalized your site because you had too many adsense placements. I think Panda penalized your site because your site did not generate enough quality signals.
I suggest you look at how to build out your brand.
-What original content or service do you provide?
-What would help your users that isn't available already?
-Is your content current and up to date?
-Do you collaborate & cross promote with other well visited websites?
-Is your website simply good enough? Why not make it better than good enough?
-What unique value does your website provide?
