I think having it all physically in front of you is a good idea.
I had mine written out on my computer but when the time actually came I was getting the egg out, doing bsf, taking supps, getting DH his can of coke (we forgot to buy red bull), checking ph, drinking special drinks.... you get my point! lol
It can be very overwhelming. I was organised but it was still hectic and I still forgot something (red bull)! I think if you have out on the bench what you can or have a checklist then that way you aren't frantically trying to remember what you need.
