Not familiar with the Rutherford steering bearings but they seem maybe twice as deep as both the Mulfab and factory fitted ones. If the main springs were not shorter to compensate this would explain the increase in ride height, as well as the bowing when unloaded. Bear in mind though it's clear ride height was lower than correct with old worn springs highlighted by the bottom of stub axle sitting above rebound springs not just lightly resting on it as ideal.
If I was in this situation I would be discussing my concerns with supplier Rutherford/New Elms to confirm again their supplied springs are shorter to compensate for their deep steering bearings. Having said that if car drives tolerably well over rough roads then maybe things aren't too far from acceptable. As suggested it doesn't look to ride too high.
New kingpin bushes if reamed correctly to match to new kingpins will take a 1000 miles or so to loosen up, then you can look to adjusting the new Wolf dampers after a fresh greasing session. I start off with minimum damping increasing 2 - 4 clicks at a time until front of car stops nodding over any particular bump in the road then backing off a click or two. It may seem a harsher ride at this point but you soon realise the ride over bumps is overall more comfortable due to reduced rebound.
Although you mention turning steering whilst at rest you don't mention if rebound springs are free enough to turn by hand when in straight ahead condition. You can find how close you are to the optimum by having someone else pushing down on chassis via front bumper to see if a little extra main spring compression free's trapped rebound springs to allow them to turn.
