To reboot, Click Device, then click the System Settings > Reboot/Shutdown > link.

FMC is not free, it is a licensed product which you must purchase. If you change from local Firepower Device Manager to FMC-based management you will lose any configuration currently on the device (except the management interface and associated  bootstrap information like management gateway and DNS servers etc.).
