Yes, you're on the right track John Zen.
If you want to have multiple orgasms, I suggest reading up on the experts: women!
While it's now commonly known that women have the capacity to have multiple orgasms, there are still women who don't have multiple orgasms, and even some women who have never had a full orgasm at all.
I suggest reading up on articles that help women achieve multiple orgasms, the same rules generally apply to men. Try to stay relaxed, try to feel pleasure circulating all throughout your body. Don't try to rush, which is difficult considering that most people are taught that masturbation is a no-no, and masturbation, being the best form of practice, is where guy normally learn what gets them off fastest so they don't get caught, so they never learn how to prolong or enhance the experience. So aside from learning a new skill set, you gotta unlearn your old one!

Now as far as things like "locking" and "contracting muscles" and things like that, well, a lot of that stuff has been taken out of context. Those are techniques suggested to use once you get past the point of no return, that keep you "in the game". However, the method of having multiple orgasm does not involve going past the point of no return- those techniques are last ditch efforts which, basically, are how you deal with your failure, and are NOT supposed to be used as the primary method of how to have multiple ejaculations.
Relax. Also, pay attention to your body and how it responds. Eventually you will get a very good feel of all the muscles involved in the process, and then you can gain control of them. So you reach a point where you have a good feeling of all the muscles and areas involved in orgasm, and learn to not involve the muscles involved in ejaculation.
Basically, it's just like learn to control any muscle group that isn't used daily- at first you don't feel anything in the area, most people tell you that you can't voluntarily control the area, then you start to feel it, then you work the muscles, then they get toned, then you can control the area at will. In my experience, the only way you are going to do that is through observation and feeling, which are aided immensely by relaxation.
Also, Stoner Shadow Wolf makes great points as well that you should consider in the process as well. Too relaxed, and you'll lose the arousal!
