How would Shira learn something as powerful as the 8 Gates? Lee learned from Guy and Guy learned from his father. I think it would be complete BS if Shira somehow found a Suna Taijutsu master to learn from.

Maybe Gaara told Shira about the 8 Gates because Lee was the first person to physically hurt him and it's high level taijutsu.
