Wokka - I am in the same position. Going through all the links will be totally time-consuming and it may not be perfect, but I think that's the only option other than to wait it out.
I've done the other suggestions - mainly getting high quality, editorial in-bound links without keyword anchor text, and my site continues to fall (except for long-tails)
Also, my site took a hit the same exact time as yours.
