Most pianists will skip this very fundamental step in learning how to approach jazz harmony on the piano. Just because it's simple doesn't mean it isn't worth learning. Bud Powell started using these very simple voicings in 40's and they are still used by almost every modern jazz pianist today. My favorite examples of 2 part (and 3 part) shell voicings come from any of the Bill Evans solo albums. You should check them out if you haven't already and are looking for some practical applications of this exercise.
Feel free to experiment by trying out different combinations of shell voicings while working on your favorite jazz standards. Take the exercises as slow as needed and you should have no problem learning these voicings adequately.
