As far as starting him with just a snare and rudiments, if I had been forced to do that I would not even have started playing. Which some might say would have been a good thing, but I enjoy it.
Most times, I'm glad that no one forced me, but there are times when I wish I was better rudimentally. I have a feeling it's like language: the earlier you start, the easier it is.
With the prevalence of YouTube and other tools not available in 1977, it would be easy to sit the lad down with a video of his favorite drummer and say "y'know, it'd be easier to play this way if you knew how to do this." That argument wouldn't work if his favorite drummer is Patrick Carney or Meg White, but I think you get my drift (no disrespect meant, I love both of their bands). :)
