Tip 1- As long as the stick is fairly straight, it really doesn't matter. The old time players almost always played with a cue off the rack. The tip is what really matters.
Tip 14- Sorry, but those aren't three strokes. They are 3 different places to hit the cueball. They employ the same stroke on all three.
tip 18- The better you get, you will find that the less you want to roll a ball. When you do that, you are asking for trouble. And, if you are just rolling balls in, good luck on position. You don't need to slam them in, but you do need to 'shoot' them in.
tip 22- First time I have heard that one. I've always heard plan 3 shots ahead. You have to know what side of the next ball to get on to get to the 3rd ball.
One other thing I think is important for a beginner that you left out. How to stand and get in a semi-decent stance. You want your head over the cue, your elbow over the cue, your shoulder over the cue. All your ducks in a row. Many beginners have no idea how to stand. And for some reason, many of them just don't bother to look around and see how others do it.
Other than above mentioned items, not bad for beginners. I see you have been on here for about 22 months and already have 6 posts! Don't slow down any! (feel free to contribute now and then)
