Seems to me, if you are getting good live rock, you'll be jumpstarting the whole process. I'd approach it like this:
1. Put live rock in tank, let it sit a few days and test for ammonia to see if there's die off. No die off, go to step 2. If you see ammonia, wait until you don't, then go to step 2.
2. Add livestock gradually. A small collection of hermits, to start perhaps. Keep adding slowly, allowing the germs to catch up with the livestock.
Again, that's how I would do it.
