Yep, turn the volume high and let her rip.
I would keep the power amp connected, although it is more than likely not necessary. I do not know what preamp you have, but the ones I have owned all had output coupling-caps, which will allow the output tube/transistor to pass the AC signal onto it, irrespective if the pre was connected to the power amp or not.
I am not sure what the effect would be if your output transistor is directly coupled to the outputs. You definitely wont be hurting anything by keeping it connected to the amplifier.
