This
should be ample time for the OP. They are will be staying in Kyoto for one night, and staying in Tokyo for two nights before heading to NRT.
But it might be worth stressing that to have the Takkyubin service guarantee delivery of your luggage to NRT in time, it would perhaps be best to request this service either at KIX itself or on the day of arrival at your hotel in Kyoto (rather than at checking out time).
