One thing I like to do is once the parts are done, I put them on the cheaper shelves you buy at the big box stores. You'll be surprised the amount of stuff you can stack in a significant small amount of space.
I do one or two resto a year, usually antique tractors, so m y parts do not stay very long, and my memory is usually still fresh about were and how parts go.
You are on a good path, keep on going.
