Two real ways to go about it, it works about the same as learning guitar for a specific genre. Either find someone competent in that play-style to tutor you, or take a beginner-intermediate class in piano. Up to that point it will conceptually be similar. Once you feel like your basic technique is sound (rolls, fingering, rhythm), start learning songs you like. You'll pick up the specific techniques you need as you go.
Taking a class early on is important though. You'll ingrain bad technique if you're entirely self taught, and reteaching yourself later when you realize your technique is holding you back is absolutely miserable. Taken from experience.
Thanks! I share that experience - I've been mostly self-taught electric guitar, only to realize many years later that my unconventional (but seemingly natural) way of holding the pick is completely messing me up :O
