Landowners really aren't anything to worry about as long as you're respectful and stay on the river. There are a few diversion dams, but they shouldn't cause many problems. Haven't seen it since the landslide a few weeks ago, but i think they cleaned it up.
Shuttle is easy, just be in and out between 8am and 8pm at the put-in, otherwise they lock the gate. The put in is steep, use a rope to slide the boat down the hill and you'll be all set.
