Really difficult!!!!

Okay, i'll start off by admitting I'm new. My point is that I've read so many replies saying to research more. So I have done this as I still continue. What I did find was a lot of information. What i need to know is just some clarifying things. Such as:

Does this work? I know it does or all this would be pointless but does it mess up?

Will it work on all DC's?
Has it messed up any DC's?

And the other questions:

I've realized you need a boot-cd so i got Utopia bootcd. I think you create this with DJ?

To copy games I know you need Iso, two files 1st something and a bin. This is where i get confused. Different people say to use different programs. I've read plenty of tutorials. Do you put in the game cd into your cd drive and then use these programs to get this stuff or do you use your writer to get them, then what do you do, just copy those 2 files?

If I'm on the right track as a newbie let me know?
