Perhaps what you need to do is ask yourself what you want to get out of this car? Do you want to be simply drive it around for fun? Do you want to make it a show car? Do you want it restored like new, or restomod it to your tastes? These are all valid questions that will help you on your quest.
The other thing to do is to not look at the whole project, but look at it in stages. Disassembly, restoring the parts, reassembly, etc. A lot of people who have never restored cars get into trouble when they freely start taking things apart, then realize they don't have the knowledge or desire to put it all back together. Many people will go slowly and start with a driver car and slowly restore different areas while still being able to drive the car.
As far as what steps..well.. subframe restoration, then suspension, sheet metal work, brakes, brake lines and fuel lines, electrical, body work, engine, transmission, etc.
There are several good books you can buy that will go through the different steps and lead you through the process:
Read, take your time, write down notes and steps, and remember to bag and label all your parts as you go along.
Finally, try to have fun with it. Restoring a car is supposed to be fun and relaxing, not stressful. btw: Dont be afraid to talk to others who have restored cars and get advice, or have them help you as you go through it all...
