The WT have used external lawyers for years. I don't have documents on this but I am sure there will be a paper trail to support this around the web as the WT has never hidden it and it's hardly a scandal - "multi-national corp uses external lawyers to support internal legal capability" is not exactly news.
The printing side of things is all rumour as far as I can tell. I think we just need to wait and see as the paper trail confirming this, if it is true, will come to light sooner or later. Again, even if it is true it's not exactly a scandal except that the WTS has pumped it's nuts up about doing things inside the organisation for years and years as evidence of Jehovah's blessing and how the organisation will be able to do anything in the New Order.
