It shouldn't be that surprising. The Falcon 9 and Space Shuttle were two very different beasts and have different flight patterns. The Space Shuttle had additional thrust during the first part with the two solid-fuel boosters vs the Falcon 9 with no boosters, just 9 engines. Also the Dragon had some dampening between it and the Falcon while the Shuttle had no dampening, it's three engines effectively was the first and second stage rockets.
As for the second stage, the Falcon second stage has one of the same Merlin engines as first stage, just with a larger nozzle to improve thrust in a vacuum. Unlike the Shuttle or the upcoming Centaur second stage, the Merlin has more thrust but isn't as efficient. Much of this is due to it using RP-1 (highly refined kerosene) instead of liquid hydrogen, which the Centaur second stage will use and the Shuttle used the entire time. The Falcon second stage is going to be more powerful but be done quicker, which keeps it running fast and hot all the way to orbit.
Docking should be smoother. It's entirely automated, which lets it get exactly the momentum needed to dock without any extra which would cause the jolt. I expect all automated docking will be almost equally as smooth as Dragon's.
