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