ask yourself: is there a good reason to know these things in detail or is it the thrill of knowing the occult? That will clear things up in your head. Personally I think that if you're asking this question you're doing it with the wrong motivation, but that's up to you to find out (rather not through experience though).
About the healing stuff, don't do it. Don't go practically in any case. You got the name of Jesus to heal, something far more powerfull and doing otherwise will put you in a very dangerous position.
