This is the way to go... I do presentations for large audiences (in the hundreds) at least once a month, my secret sauce is:
-Keep the slides simple, not too much text. They are there to hear what you have to say, not to read the content on your slides... the slides should call out the big takeaways or key points but it's your voice over which really should be illuminating the topic.
-write out what you're going to say. Even if you don't use these "notes" for the actual presentation, writing it out is a great forcing function to make sure your commentary is well organized and succinct, and it connects some dots in your brain so that your speaking part is smoother and you're not searching for the right word when you are doing the actual presentation.
-practice the entire thing end to end, out loud, at least 1 day before the actual event. In addition to the obvious benefit of practicing, this is also when you hear yourself saying the words out loud and this is a great feedback mechanism. Many people (students to CEOs) read their written work (documents etc) out loud as a best practice for making sure it really flows. This is also when you get a feeling for time... I can't tell you how many presentations I've attended which are time bound (e.g. meeting is 30 minutes long) and we don't get to the end of the presentation because they never did a real dry-run end to end with a timer.
