For sure, they definitely do quite a few inspections to ensure the vehicle is ready for flight. Though I would expect the number of required inspections to drop as they gain confidence in how the vehicle looks post-flight, and they are getting a TON of data in that regard.  
  
 Also I would expect them to be doing these same inspections on any newly built rockets as well, so it shouldn't be adding more work that otherwise wouldn't be done for a new fresh rocket.

It is much more than inspections. /u/XBL_Unfettered said extensive rework and NDI and that is probably putting it lightly. I think last I read that refurbishment costs on a core are nearly 50% of the original production cost. I don't see how it could ever be 'no touch', it will likely (best case scenario) just be a highly efficient refurbishment program that can achieve a 24-48 hour turnaround time.
