"I would concentrate on the links reported in the Webmaster Tools on Google"

Google said:

If there are links to your site that cannot be removed, you can use the disavow links tool. Please note that simply disavowing links will not be enough to make a reconsideration request successful; we will also need to see good-faith efforts to get inorganic links removed from the web wherever possible. Make sure that your disavow link file is correctly formatted, for example, be sure to use the "domain:" keyword if you wish to disavow all the links from a particular domain.

Hope that helps as it is very clear said what they want!
