Chest-Try and substitute dips or declines for db press. You already hit that area with the barbell.
Triceps-Lying overhead triceps press and skullcrushers are the same thing. It would be too much on your elbow joint.
Back-Stiffleg deadlift is predominately a leg/hamstring exercise. Plus you are already doing regular deadlifts anyways. Substitute pulldowns.
Shoulders-Clean and press to front for 3 sets, then the back for 3 sets? That has to be a typo. That's like saying you'll do barbell bench to hit the middle of the chest, then I'll do some dumbbell presses to...umm, hit the middle some more?
Legs-Squats are meant for legs pure and simple. You're going deadlift crazy for some reason...
