I know nothing about the brand you said you are getting so I can't comment on those. Unless you are building a show car, I would forego the slotted and cross drilled rotors and just get high quality pads. They are a waste of money IMO. I would go with some Axxis Metal Master pads. Those are what I will be putting on my car next and I have ridden around a road course in a modded 240sx equipped with the same pads. Stopped predictably, quick, and never faded lap after lap. And the car was being pushed very hard.
Braided stainless steel brake lines would help pedal feel a lot also. Those are the only two mods you really NEED for great breaking unless you wanna splurge for a big brake upgrade which is $$$$$
