Going native has the advantage of giving (potentially) the best performance on each platform. Things like infinite scroll, animation seem to be smoother using native code. The downside is having to know how to code in two languages and having to maintain two codebases. Responsive site is the logical first step, since you want it on the Web anyway. You can use most of this to build your hybrid app. I've used Cordova and it works well for basic apps, so this is the direction I would take.
