1:35 to 2:45 is good content, man. I like the idea of doing full throws first then doing drills, although I do have a couple "primer" drills I always do first. Definitely on board with throwing before lifting.
Just doing it? Hard to understand what you are asking, it is kind of just how you throw. Throw it more until it can become comfortable. And always continue to push to get stronger which should make it easier
