I can't believe nobody has mentioned replacing the hoses with braided steel. Those make a huge improvement in pedal feel and brake response.
I'd also recommend the '07+ upgrade using decent solid rotors such as Centric if OEM ones couldn't be found for a fair/good price. Aim for higher-performing pads rather than rotors. Next step would be hydraboost but that can be done down the road.
Slotted and/or cross drilled rotors are more for looks on daily street-driven full-size SUV. I'd pick slotted over drilled, but any of those eat up pads faster and increase dusting.
I had cryo-tempered slotted Stop Tech rotors with Hawk LTS pads. The rotors were a disappointment within the first 1,000 miles. It could've been the combination of that pad on that rotor, but I was done with them and looked forward to their replacement which finally happened a few months ago. I had all four stock rotors resurfaced (glad I kept them!) and got ACDelco ceramic pads front and rear. Fully flushed the fluid and gave 'em a rigorous bed-in and I'm totally satisfied. No squeals, no shakes and the total brake job was (IIRC) under $200. Braided lines wasn't in the time or money budget this time around since I'll need 6 lines. But they'll happen eventually.
