I need at least 50 different "categories" or "custom fields". Everything from Contact Info like Name, Address, etc. to specific information that I would have to uniquely name. I am getting extremely confused on how to do any of it. Is there a tutorial on here, or something? I am really new at this.
Welcome to Civi! A great place to start is this wiki post about Groups vs Tags vs Custom Fields:
There are also sections of the Civi book that might help:
Under your 'Administer' menu there's a 'Customize data and screens' and then a "custom fields" option. There you can add all the fields that you need.
