Not that you need to do them all but definitely a good place to start. I often get the comment from sellers after they get their home ready for sale "I wish we would have done this sooner so we could have enjoyed it all fixed up". So it is a good list as well to getting your home looking it's best for you to enjoy personally.
Give me a call if you would like a personal consultation as to what you should do to prepare your home for sale. Do you need a Professional Equity Assessment of your home as well?
