I recently got my rims and now i can see the rotors. I looked at them today and asked an mechanic to check them out, He said i needed to replace both pads and rotors on my front.

What do you guys recommend me to get? And where?
I want pads with less brake dust! I just got my rims and I have brake dust all over them from few hours of driving. For rotors I want maybe slotted rotors.

I don't know much about pads or rotors. So, if you guys can help, that would be great.
