It seems the tutorial is for the whole screen (LCD+Glass) and it pretty much covers everything. After removing the screen, it's just a matter of replacing it with the new one.
My experience: I bought the whole screen and mine came without any adhesives, so I had to use a double sided tape I got previously for another screen. It's a very thin black tape and while I've read that it is not recommended, it held the screen in place. Although I am worried that it might be a bit weak for the long run. Also, it didn't came with the speaker grill, so I had to use the one from the broken screen. Remember this before installing the new one.
I bought mine on eBay.
True, missing important details. I'm about to do this replacement. I assume the replacement screen has dual side tape built in. I'll report back soon.
