My experience with the "lifetime brakes pads" from the auto parts stores is they do not stop very well at all. I will never buy them again...safety is worth more to me than money and time. As you go bigger with your build, consider increasing your stopping capacity (Google is your friend for this research).
I installed the Black Magic pads on my TJ and they are significantly better than my factory pads, but I did the big brake upgrade when I did it, so I got some benefit of better rotors (Centric) and dual piston calipers.
Disc brakes are awesome for the DIY'r since they are easy to do with minimal tools and time. Drum brakes are terrible to do for a novice, so I won't do them except as part of an emergency brake system (i.e., Ford 8.8 e-brake). Luckily almost every new vehicle has disc brakes, so learning this now will pay dividends in the future.
