Newcomer with questions

[mistermano]

Hello everyone. I'm quite a newcomer at hypnosis in general. I have some questions that I hope you guys and gals can answer.

1- English is my second language and I can understand speech without a problem, but when I can't conciously listen to what's being said (as in dshadfield78's 18-45 women), will it still work?
2- What are the main differences between the hypnoses that require and don't require you to be in a trance?
3- Is there a problem with listening several different files during a day?
4- I want to make some of my own, mostly self help for myself, though I'd like to make it one of those loops that you can leave playing while you sleep or while you can't focus on it, can someone tell me if I need to do something different?
5- Is there a program that lets me create my own binaural beats with a sound I want? Or would it be better to download already made ones?

On a kinda unrelated note, I've downloaded the DNA Activator from here: http://www.xtrememind.com/freeware.htm . I'd like to know if anyone from here did as well and the results

I think this is all for now. Greetings from Brazil!
