For a beginner or intermediate, pads and fluids are more than enough.
An excellent pad for both street and track are the Endless MX72's. They work well for a heavy car with ABS and should you need a little more bite, step to the ME20's. I have found Endless pads are quiet enough for the street, and are fairly rotor friendly as well. The are certainly not cheap but they seem to last longer than most. Also, Endless RF650 fluid has an excellent wet boiling point and gives you a very firm pedal too.
If you don't know about Endless, just google it and see how many Porsche Cup cars are switching over to Endless pads.
