I also started out like you, my first brew was AG on untested equipment, I had a perfect brewday! My advice would be write down all the steps in order, with the proper times ect. I had my hop additions pre-measured and in labeled bags. first bag was labeled "#1 1.0oz cascade @60min, set timer to 30min." next bag was "#2 0.5oz cascade @30min set timer to 15min." ect. it really ensured I did not forget to make additions ect. or forget to set the timer for the next addition.
