I'd be shocked if SpaceX didn't treat this launch with all the care and preparation and expense of a manned NASA launch. Any issue with this launch would ground F9/Dragon and require full investigation the same as an issue with a NASA launch.
No. Falcon 9 never costs less then $50-60 million for costumers. $30 million is maybe internal cost for SpaceX (likely SpaceX is lower by now).
The Dragon however is more expensive then the rocket itself.
