That's pretty much it. His strength is his ability to kill people quickly 1v1, having enough mobility to quickly gank different places on the map, and having a very powerful combo that can be used to harass in order to set up for a kill.
Focusing on laning with him isn't really something you do. You lane so that you can kill people and then kill more people.
EDIT: Also the only reason you ever R up close and then Q to harass is because A) They've just used some of their abilities trying to harass you or to kill minions so you can just walk away B) You have your e up and have better speed than them, so if they are already backing up you can just slow and then walk away or C) you're not actually harassing, but killing them.
Most of the time you harass by faking going in for a last hit and then Qing them and Ring away if you need to.
