Definitely flush the brake fluid. You should do it about every 2 years regardless of mileage. Brake fluid absorbs moisture, moisture causes rust, rust pits cause leaks in pistons and brake cylinder bores, which costs you more money later (brake fluid is cheap).

I'm on my stock brake shoes after 250k. I bought some a while ago assuming I'd need new ones, but when I looked at them they are going to be fine for a while longer. Check them, but you probably don't need them yet.

Stay with stock pads (they are not expensive) if you are fine with the stock brakes, try some of the others mentioned if you want more power.

Brembo rotors are at least as good as stock, and cheaper. If they aren't grooved and don't pulsate, then I wouldn't bother turning or replacing them though.

And if you're turning or replacing rotors, repack the wheel bearings as was suggested.
