If you're a newbie go stock, no reason to wait or waste money on stuff you don't need yet for a hobby you're trying for the first time. Hell, maybe it's not for you and it'd be a shame to spend hundreds or thousands of dollars on equipment that will go unused.
If you get into it the brake pads and fluid will be the first necessary upgrade. Lots to read lots of opinions but you are fortunate to have a quality car that will hold up to light track duty very well.
Have fun, there's no heroes or trophies at track days.
