Will my site ever get back into Google?

This is getting ridiculous

Ok, so I know I am not the only one who took a hit since May, but despite all of the things I fixed on my site just for Google, my site keeps getting lower referrals from the worlds biggest search engine. Despite this, I keep getting more and more referrals from MSN and Yahoo. So my efforts, aimed for Google, are working well for MSN and Yahoo, but not for Google itself. This is a little disturbing because I may never get back into the rankings.

I want to go over all of the "fixes" I have made to my site. I learned so much during the past few months, although nothing seems to be working:

1. Fixed the canonical problem (non www to www)
2. Fixed all my urls to absolute
3. Erased my meta description tag (they were all identical)
4. Cleared any page that could have been duplicate content (even tho that shouldn't matter)
5. Contacted Google about possible hijacked pages. Google removed those pages.
6. Redirected the index page to / (to eliminate any possibility of duplicate content)
7. Moved the site to a VPS to its own dedicated IP address (Perhaps I was in a bad neighborhood)

Now with all of these efforts, I keep getting less referrals from Google as the days go by. I just don't get it, I can't even rank for the most absurd keyphrases. Lets say I invented a keyphrase, and other sites link to me with that keyphrase, those sites will outrank me still! I don't know why Google is doing this to my site....but I took extreme measures to fix this, to no avail. Is anyone else in the same position, and assuming my site is following the rules, has good content, and has decent inbound links, do you guys think this could be a glitch? Will the glich be fixed during the next update? And do you think I was perhaps in a bad neighboorhood while I was in a shared IP environment? I took my site away from the shared IP just a few days ago, and got my own dedicated IP just in case.
