Thanks for the responses all.

On the pad front I think I'm going to stick with the ds2500 (is that a pun?).

On the state of the current brakes, the rotors aren't too worn, down 0.2 mm from standard all around, but they do have grooves forming. The pads are at about 4-5mm from a visual inspection, which is 25-30% of original thickness. So the brakes don't absolutely need to be changed right this moment, I could just do fluid (which the car needs badly). Still going to change them. Going with new rotors for now, I'll still look into getting the originals resurfaced.

'Final' list:
-RBF600 - 1L
-DS2500 front and rear
-OEM rotors front and rear
-OEM brake lines front and rear
-Brake system lube - whatever parts store has I guess. I swear I had some...
-Slide pin sleeves - so weird

Note: Slide pin boots look good to me without disassembly, if I do find a bad one during the job, the Toyota dealership can usually get stuff next day if they don't have it on hand.
