The first recovered stage, F9-021, has already been static fired and will likely end up as a monument outside of SpaceX HQ as they've filed an FAA request to do so.
The second recovered rocket, F9-023, will be relaunched. It has already been static fired with no announced problems. Elon said it'd be a few months before a customer was announced, but the general feeling is that it will be an SES satellite as SES has already publicly expressed interest.
