Yes, the hihat part is easy to play, and it really opens up to possibilities. Shuffles are generally like what you said, triplets without the "and" counts. Its fun to play around with it too, like accents on the "ah" counts make the horse galloping sound like a railroad train. It's fun to play around with the shuffle rhythm as discussed in the other thread, it can be applied all over the drumset.
The difficult part isn't in playing the parts. Take the Rosanna shuffle for example, it's difficult to play it up to speed, but its even more difficult trying to make it feel like Porcaro's playing.
