Youtube has many videos on quilting, some are beginner's classes. It also helps if you know someone who does quilting in your family or neighborhood. One on one help where they can start you out and you can see and follow what they do, as well as ask questions as they arise. It will help you to take a class, you can learn with others and you will be able to ask the instructor questions too. It does seem overwhelming at first, but once you get started you can go at your own pace. It seems you are headed in the right direction to begin. There will be others in the class that will be starting new too. If you have a great machine, that is half the battle! Try reading your manual and take some scrap fabric and get used to how your machine operates, correctly threading your machine, trying to sew long strips of scrap fabric, practice sewing a 1/4" seam. If your machine doesn't have lines etched into the throat place, you can measure 1/4" from the needle, outward and put a piece of masking tape down with a line at 1/4" parallel to your presser foot. Then, put two strips of fabric, right sides together, pin with straight pins or just hold them together and sew your quarter inch seam all the way down. Just practicing getting an exact 1/4" seam is a good skill to learn.
Hope that is clearly described for you.
