You can add more rock to an established tank. That dry rock will likely cycle and go through its own uglies for awhile, but it shouldn't crash the tank or anything like that.

Just fine to add them right away.

I agree with the others, you are fine to just add it in.

Fine to add dry rock. It won't cycle as such, it will just gradually get inhabited by bacteria and small organisms and alga etc etc.
