Hello Joe: You're right that too much content delivered by PPT can be overwhelming for students. One technique to augment PPT's is to post a question and ask the students what they think are the likey "bullet points" or emphasis taliking points. Then, the lecture points can be reviewed with encouragement to students or essential points that were on track. Students like and need to feel engaged. When they sense they're getting that from their teachers, I think they're going to always respond better. Your suggestions are good examples!
