If I were you, I'd take that basic template and before going to the working sets, I'd "warm-up" with a lot of triceps extensions (triceps pressdown) with like 15-20-30kg, then some upper back work and chest work. That's around 300 reps before starting to bench/OHP.
That way you work your tendons and so on + hypertrophy (it's not a lot load wise, but 3 times a week with 100 reps, that's 300 reps for triceps + the bench/OHP work).
I'd do some traps/reardelts 2 times a week with side delts and maybe some front raises, just in case. Do biceps and forearms 2x a week just to stay healthy with that amount of pressing.
I'd do more lower body if I were you. A lot of hamstring and glute work, and of course some calves, like I said - just in case for injury prevention.
I believe in frequency, that's why I prefer doing so much light work + some heavier lifting for bodyparts, cause you get enough specificity out of benching 2x a week on average.
das my 2 cents
