I have a question about how to play the "triplets" (not actually triplets, just groups of 3 chords that run throughout the entire song - minus the middle part). For example, the song starts on a G, then plays a chord three time, that group is what I'm wondering about. Should those be played mostly from the wrist and arm? My teacher told me I should have more "bounce" but I'm not sure if I'm doing it right.
NO the arm is exactly what you should be using, but I would wager you are thinking of each chord in the group of 3 as needing its own up and down movement.Instead, try thinking of the 3 chords, as one movement, with a slight accent on the last chord, and use a very subtle and relaxed writs, and allow the weight of your arm to bounce through the chords. That way you are playing virtually tension free and your tone will be much nicer than in you use only the fingers.

Playing with the fingers only is a stupid idea.
Personally, I think that the "bounce" technique is all in the wrist while the fingers simply aim which keys are to be played. It's kinda like dribbling a basketball very quickly. You push the ball down with just enough force to maintain the same amount of energy.
I'm convinced this is an illusion, myself. Hold your forearm with one hand and try to move the hand up and down as fast as possible. It really won't be quick. It's extremely hard to change direction fast enough to simulate three rapid chords. I'm not saying the wrist would not actively contribute anything, but moving from the wrist through braced fingers is not a naturally fast movement. The fingers need to provide at least something, for any real bounce.
