Unless you are planning on road racing or drag racing why bother upgrading the brakes? Unless you find a good deal for a better braking system on the net, then go for it. A good set of pads and the stock rotors should suffice. I'm no brake expert so I'm sure someone else will answer that part of the Question better. As far as mods, I would go with the gears first, exhaust second, then underdrives, etc... There are alot of ways to go depending on what you are trying to accomplish.
