I measure out hops, finings, etc. into custard cups, put them in a row, and put post-its under them labeled with the name, quantity, and time. Similar to baggies, but if you're indoors, less waste, and easy to read.
I have two wooden spoons I use for measuring (one for my 5-gal kettle, the other for my 8-gallon), calibrated with gallon markers.
I almost always mash the night before these days. I'm an early riser, so I will often have a brew done by mid-morning.
I get my gear out the day prior, but on my to-do list is a brew-day checklist, so I don't keep going back for that one little thing.
When I was a new brewer, I would open my fermenter every day, obsessing about the brew's progress and taking lots of measurements. Now I don't open the fermenter until I have to (to add something) or until I'm reasonably sure the beer has finished fermenting.
