For the tires, I'd scrub them down with some dish soap. Cuts through grease pretty well. That and go easy on them until you get the feel for them. The brakes, run the bike to 10 mph and apply the brakes with moderate force. Rinse and repeat a few times alternating between front and rear. Let them cool a bit and then repeat from 20 mph. Same procedure at 30 mph. Continue up to about 40 mph and slow to about 20. All using moderate force. That should bed them correctly and you should be ready to go. I'd be easy on them for the first 50 or so miles and give yourself plenty of braking distance until you're good and confident with them. That's my 2 cents.
