Yes. I've been following each of these for a few years (except for the big & threatening thing, I'm pretty short) and no client has ever completely escaped payment on me.
Everything stated here is the gospel. If you run a consulting business, follow this to the letter. You will always get paid, eventually.
My policy is that when it comes to getting paid, I am aggressive as hell. I treat every invoice as if the client will be delinquent. You can be the nicest person to work with, but be the most vicious asshole on the planet when it comes to billing. Establish that up front, and they will always pay.
