Hello Everyone!

I am writing regarding the following proplem I have confronted recently:
I am trying to add more custom heroic affixes or custom itemflags to my WOTLK 3.3.5 repack. Unfortunately I am not an advanced PHP Code Editor,  this was my first time I encountered with it, so I am at a very beginner level at this point (yes, you can blame for me that). 
So the problem is that I am stucked at this point:
(Here are two links, which should serve as a tutorial :

Pick a nice empty spot with 60 empty bytes. I chose 009DE3C0
Write down the address you choose as OFFSET_4
Calculate OFFSET_4 + 0x13 (Hex Calculator - Addition, Subtraction, Multiplication & Division), write it down as OFFSET_5.
Calculate OFFSET_4 + 0x24, write it down as OFFSET_6
Starting at your OFFSET_4, enter these lines, replacing OFFSET_# with your addresses:

I don't get it where should I start  replacing these lines. 
Should I replace the offset 4,5,6 with those lines in Notepad or should I look for someting in OLLYDBG?  Please guys, help me understand the process without getting me discouraged.

My dream is to ad Mythic  and Mythic Titanforged to my database to become available to set as Itemflags for my custom items.

I would really appreciate if anyone could write a detailed. beginner friendly,  step by step guide to help me learn this. 
Thank you in advance!
