Paul, sounds very normal to me
One thing I did (and still do mentally and sometimes in hard copy) is go over the steps for each process, writing them down in a notebook and going over and over and over and over and....(you get the idea) each process till it's committed to memory. Than when I'm building, I have the note book on my bench and when I think I'm missing a step, I refer back to the notebook.
Take a look at Charlie Hoffman's Step by Step 6 page documentation of guitar building. Years ago I printed this off and just read it over and over and over and.... trying to get it into my memory. Of course I've chosen to do some of my steps in different orders than this, but it's a good detailed list of the steps or process' to guitar making.
Best thing is you're having fun and learning (and staying out of trouble my mother-in-law would always say, but what does she know with TAS and WAS always rearing their ugly head)
