thats a must some of those old steps when you are doing a project can be somewhat tricky to remember exactly what commands are needed for the desired results !
I wrote an "online hints manual" one day when work was slow about 15 years ago and msoffice first started being useful. It gets constantly updated with every new release of autocad and any stuff i really need to remember. Now I find myself printing it out and handing to every new drafter or engineer that starts in our office. I find that every drafter does things a different way, or as the saying goes, "I'm a great believer in CAD standards, that's why I use an excellent set of my own". By giving them an example of how I set up a drawing will hopefully lead to some consistancy in drawings produced by our office.
I use an excel file, similar to what your are doing - but for my system customization. I can add screen shots and links.
I've divided up the major items by tabs, and can re-arrange and/or modify my thoughts and comments as time goes by and AutoCAD changes. Also it helps to rename the file w/ the current dat each time you've updated - this allows for some legacy retreval if neccessary - and since it's all digital you can email it to yourself.
I'd suggest that anyone thinking of doing this look at M$Office Onenote - it's very flexible.

I have kept an cheat book since I have been working in CAD also. When I have a problem that happens once in a lifetime and you spend a lot of time to correct the problem, then it's worth writing it down. If it happened to you there is a good chance that it will happen to someone else and it's a better chance that I will not quite remember what I did to fix the problem. I also have "The Help Book" that includes tips and tricks and other information to help in the office for all to reference.
Autoad includes a huge PDF of called acad_acr.pdf (acad command reference) that has all of the commands and systame variables listed in alphbetical order with a small blurb of how to use them and what they do. I find alot of cool stuff just browsing and if I need something specific adobe has a good search function and I dont have to write anything down.
You can find it under your Program Files/autocad 20xx/setup/docs
Don't try to print out the whole thing though, its 2064 pages long!
