what cabmando says, bag the parts and label, I kept them in recycle bins slotted in order of how removed.
One thing I regret is not always cleaning the parts when I took them off. I wanted to make sure each bolt went back where it came and the color marks and dirt matched up with pictures from removal-if I cleaned I would need to label each bolt so I waited until reassembly. Not sure what others do about that.
Brought as many parts as I could to the basement to get them out of the way after I stepped on, crunched parts and kicked small screws skidding across the floor into hiding places too many times. Basement became my cleaning, wire brush and painting area far away from the car.
I kept track of major steps and tool needed by writing on an erasable white board next to the car (occupational hazard). When it filled up I started taking pictures at the beginning of each stage and when I wanted to make notes to myself and that worked out great, made reassembly very quick and by going backwards I didn't do dumb things out of order. I just kept laptop open next to Bentley and factory manual (and able to search Pelican/Rennlist when needed)
