Unless you are filming with a real film camera (i.e. in the +$80,000 range), there's almost no way/reason you would have true 24p and even need to think about 48048Hz. If you have a TV source and you inverse telecine, or a "24p" camera, 24000/1001 is the rate you should use (and get). No need to convert from 23.976 to true 24p. The film TV rate in the US is 24000/1001. And yes, they do master at that rate (on DVD/Blu Ray). Sorry, I missed your question on mastering on my first read.

Edit: They may master the studio original at 24p/48048Hz (or a higher sample rate with similar proportion). This is probably because the whole system is built on it and it's hard to teach an old dog new tricks. But such a slight slowdown is in no way noticeable to the viewers, so it doesn't really matter. The PAL speedup, however, is noticeable.
