All the front discs should be vented (the rears are solid), cross-drilled is another matter, and not the way it came it from the factory. Balo and Brembo seem to get good marks for OEM disc brands, I personally like the Textar OEM the best. Textar is what comes in the Mercedes Benz box from my dealer. I think Pagids are more likely to squeak a bit, but are otherwise a good brand too.
