As other have said, I would change the brake lines out to stainless steel braided first.
Unless your rotors are warped or close to spec (as far as needing replaced) I wouldn’t change them. If you do get a good set of blank rotors (not slotted/cross drilled. Back in the day they used to vent gases released by the pads under heavy racing abuse but anymore are “bling”).
Pads: You’re going to have to deal with brake dust, but get a more aggressive pad.
One thing I have yet to see here is pad break in. Before I put the pad on, I make sure it’s flat. Take the pad and put the pad material face down on the concrete and press on the pad lightly while going up/down then left/right. Clean off the pad and install.
Once everything is done (pads installed, brakes bled, brakes pumped a few times, etc.) then take the jeep out somewhere where you can do 5 run of 40-5mph while HARD on the brakes. Then 3 runs of of 70-20mph hard on the brakes. This is transferring brake material to the rotors and needing the pads. I do this to all of my vehicles, including past track cars, and has always done a great job slowing my vehicles down.
Big brakes are great if you have money to waste or are in a high end racing, but I bet most would get by with the above. Just my $0.02.
