A lot of people argue about this. Some people say that crossdrilled/slotted rotors can crack more easily and some wont. But slotted/drilled run cooler than standard flat rotors because they let the air in.

As far as pads, with ceramic you will have very little if any dust but they wont last as long and ceramic carries no warranty. Its fine to get semi-metallic just get a good brand.

Everyone will have a different opinion on this so do what you want to do.
