I'm a bit concerned that you are pinning all the blame on those links. There are hundreds of other factors that can cause drops too.
If it isn't too late I recommend biting the bullet and launching a whole stack of new websites using one of the article writing companies out there to create fresh unique content. It means hard work, investment and a wait of, probably, many months before you reap a dividend but then so do nearly all other types of business.
In the meanwhile, personally, I would do nothing about your present site. It may well bounce back, and messing with it may cause it to sink even further, who knows. Google employees spend a lot of time dreaming up ways to keep us baffled about that and a lot of the 'advice' they give (such as disavowing links) should be looked at sceptically.
Finally: you should never have all your eggs in one website IMO. Spread the load.
