well you've come to the right place. If you wanna get started, get reading, since you said you downloaded literature.
The best advise I can give you, since you said you wondered about the burning question...
What is Ethical Hacking?
What is Forensics and how it encompasses IT?
Ponder on the result. Then after careful consideration (more than five minutes) ask yourself if you think this is gonna be the path that you will follow for the rest of your life. It does sound like forever and well yes it is. Both these branches involves daily research, and cannot be learned by just studying a manual, you'll learn as you go, that's how i do it.
Many people think security is all fun and games, believe me it is, that is if you are cut out for it. If your passion is here, then despite the hours studying/ researching, besides the deadlines which may somehow manage to be completed in the nick of time, and of course the higher ups breathing down your neck, it will never seem boring and frustrating.
I may not have the certs but I have the heart and this is what has kept me in IT security for so long.
I think I'm straying, but to make a long story short, the questions above are the most important thing to do if you want a good starting point.
If after careful consideration, this is the place for you, start reading the manuals, then come back and let the community know your progress and problems.
This is one of the forums where beginners to elites feel comfortable, so let your questions rip (with hard research done before though).
And welcome to the fold
