---- Site has fallen since Penguin, clueless as to why

I'm way to nervous to submit links to Google and disavow them based upon the reporting.
Good, you should be nervous, this really isn't something for someone not familiar with the ins and outs of search and Google even warns that the disavow tool might be dangerous in the hands of the wrong people.
But, while you're pursuing the possibility of a Penguin hit don't discount anything else. Dive head first into your analytics and tease every last bit of info out of it that you can. Then, when you're done, you'll be able to make a more educated guess as to what actually affected the site.
