I have the exact similar situation though I have been wacked on the 8th of Jan. I have cleared a lot of my backlinks and requested a reinclusion on the 16th - no reply yet. I have also done a LOT of work on my site.
After these 3 months of searching and pain im starting to think that my initial reaction was wrong - ie. I should not have removed any links just looked for more valueable ones and left the rest alone.
