Now regards the changes then your making it worse not better.?? . . . Distance from Ballnut to Z axis rear plate is too much and that long bracket will flex and resonate.
I'd just flip the plate to front and cut a slot in it and mount ball-screw on back side so the distance is less, your also protecting the screw and motor. Stick another thin plate on rear and it's fully protected and helps stiffen gantry.

Don't go with your current design you'll regret it in this form.!!
