Bedding your new pads should only take a matter of 15-20 minuts if you do it correctly. You do a series of stops each time getting more agressive. While you do this you do not want to stop your car until the brakes cool down. I'd say do about 6 stops from around 40-60mph to 5mph starting pretty easy and gradually stopping harder to where on the 6th stop you are almost locking up the tires. After you're done, cruise around and let them cool down a bit then you should be good to go. FYI, your pads may smoke and smell... Thats normal.
