Definitely upgrade the pads and fluid. The most annoying thing is to go to your first track day, feel the car getting faster, and then be limited by brakes or tires. You don't need to upgrade to something aggressive, but at a minimum make sure you're running something that can handle the additional heat. This is coming from someone that enjoyed a fun-filled first day, but had several scary moments the second day with a mushy pedal. Especially frustrating when they give you the go ahead to run solo and you try to start pushing the car by yourself.
