You will want to get a reflector for your T8 10% bulb and set that around 15-20cm above the main basking area for it to be most effective.
From what I can tell, the ThermoControl Pro 2 is an on/off thermostat so it will work best with your ceramic heat emitter overnight. If it keeps turning the basking light on and off it will be more problem than help. You could set it to monitor the cool side temp (under the ceramic heat emitter) during the overnight and to come on when the temperature drops to 19 and turn off when it gets to 23 or so. That will ensure overnight temps stay warm. If your house stays warmer than that overnight then the ceramic heat emitter won't be needed.
For your basking light, measure the temperatures with one of the probes sitting right on the basking site and either change the height, wattage, or dim the output of the basking light to achieve the proper temperature gradient. You want the basking surface to be between about 38-42 or so and the cool side should stay around 26-28 or so during the day.
