Jim put together a very helpful article that is available to you in the library section of this forum.
Most of the questions you have on finishes of the hardware, are answered in that particular article.
Perhaps if you phrased your questions along the lines of: "I see the finish on ______ bolt (or nut) is stated tp be Phosphate & Oil, how dark (or light ) are other examples typically found to be?"
I'm about to go through most of my Hardware also. I plan to print off a copy of the hardware sheet for a 67 and select the items that are correct for my car from the list. I then plan to go back and make a copy of the program if possible, leaving out the items that do not belong to my car.
Afterwards, in the new program file that I have created, I plan to upload photographs of my original bolts. I am no computer genius by any means so this could be quiet daunting for me. I am hoping that other people may chime in and say how they have done the process of documenting their original bolts against the list. I really haven't seen anybody talk about that yet, only people talking about using the list found in the library.
I only basically understand the Excel program so for me this will be a learning lesson as well.
