No offense intended, but if it's too difficult for you, than you probably shouldn't touch the phone until you understand everything. Before you start modding, you need to know how to recover it so we don't have another brick. Once you start to understand the minor things, it will be like a light switch and the more complex things will start to make sense.
I have already rooted and unlocked my phone so that's a good start haha. I will now follow the advice given in this thread and hopefully learn enough to understand these more complex concepts!
I appreciate everyone's information and responses!
