To I3 the goal is 20 reps. You'll use the same weight for all 4 sets. Add all the reps together. If you get 20 or more raise the weight the next workout. If you get less than 20 use same weight next workout. As far as switching the exercises I like to do it after a break which you'll need every 5 or so weeks. Just do a major chest exercise first then major shoulder or tricep exercise 2nd. You'll keep squats the same. Same principal on the pull days. It's not an easy workout it will wear you out with the quickness. If you do it right eat enough and get rest it will pack on the muscle and strength really well though.
