I have HPTuners which allows me to lock my pcm. I have not done this yet but now wonder if I should. Does anybody know for sure if a pcm locked by hptuners would block a Tech-2 reflash?

I think the crank relearn is just used to detect the misfires. I put in my tune and didn't have the crank relearn code pop up until 2 or 3 months later. I had it done for free by a friend at GM.
Even if you have to pay for it, it should NOT cost $130...that should have set off all sorts of red flags...
