First off, welcome to Canreef!!!
You're doing fine.
Your rock isn't going to die. Right now your tank is just cycling and the bacterial populations are growing in order to deal with the levels of ammonia, nitrite and nitrate in your tank. Once cycling is complete, you should see all 3 levels go to zero. At this point you can start adding your cleanup crew and fish. Go slowly with the fish. Remember that each fish you add will be producing waste and will mess with those ammonia levels and the bacterial populations will need time to reduce them to nitrite and nitrate.
I would give the rock at least another 2-3 weeks, if not more (keep an eye on those parameters) to cycle before you start adding stuff.
