Going on average weight & 23mm/700c tires, would be looking at 100psi f/r minimum.
For road surfaces, given you have a UK eBay link, you in the UK, live with it; UK roads are full of potholes, and you need to learn to ride round them/avoid rather then hitting them head on.
Yes, exactly. He may be running under inflated to soften the ride. Riding around works as does getting ones rear off the seat when riding over a rough patch.
