All excersises preceeded by warm-ups.

Now for my questions-
1.Is it worth doing the flyes or should i drop them seeing as the clean and presses hit my chest aswell.
2.Should i drop the pullovers and replace them with power cleans and if so should i drop good mornings seeing as the cleans hit lower back too?
3.Would i be undertraining my quads if i dropped the leg extensions?
4.Would it be worth adding another excersise for bis and tris or will that be enough seeing as they get worked in the compound movements.
