PS
DO NOT "
2. Remove all URLs from the index via the Removal Tool in WMT"
This is my opinion and I believe it is shared with many other people as well and search engine optimization community by using the Google disavow link tool or revoke links tool you are essentially consenting to doing something wrong do not do it
do not unblock 100% of your robot text only allow the links that you wish to have seen by Google. Just think of them as a parameter on the end of the link but a subdomain. It will be indexed and site map accordingly.
Sincerely,
Thomas
