You dont have to do all steps at once. You can do a little of it every time you have an hour or two to spare. I think for the whole procedure you will need roughly 8-12 hours. I think its written in a way everybody should be able to follow.
If there are still steps unclear just ask, i will see if i can help you. btw this is written for noobs, but the tips here are interesting for almost everybody.
P.S.: Once you have installed TOR you can get access to TOR hidden services and other interesting deep-web pages. If you want some links for your first steps into this hidden part of the internet just ask me. If there is a lot of requests i will write an 
One thing before you get started : most deepweb pages arent online 24/7. So if you cant reach a certain website be patient and try again and again till you get access. Another thing : you will find websites that are pretty shocking and disturbing.

;tl,dw : say nothing and ask for a lawyer, ALLWAYS ! You cannot improve your situation with anything you say (this is counterintuitive, but the attorney here has in his whole carrer NEVER heared of single case where a suspect could help his case by talkin
but he could name many cases where they made matters way worse) but you can make it a lot worse, so shut the hell up and wait for your lawyer.
Even him being a defense lawyer wouldnt talk to the police under any circumstances. You can tell your story before court AND NEVER, UNDER NO CIRCUMSTANCES, BEFORE THAT ! Even the cop in lecture 2 says NEVER TALK TO THE POLICE !!!!!
