Personally, I'm more likely to obey my own paranoia, than howard or brian's paranoia. Moly grease (real assembly lube or otherwise) all over the lobes, buckets/shims/keepers/etc, thinner lube in lifter/bucket bores, take it for a spin and whenever you and all your new parts are happy, change the oil.
Of course, yeah, cams shouldn't wear in much, it's just very light burnishing, I think the fear is that if it goes wrong before the parts are entirely happy, you get runaway scuffing and wipe it (and the motor) before you know what's happened.
The most important part of any automotive repair is to maintain the loose nut behind the steering wheel. Do whatever makes you feel warm and fuzzy inside.

From what little I've read today I believe they sell that lube for freshly built engines using new camshafts. I am not entirely sure they would recommend using it if all you are doing is a cam swap. And I have a feeling that whoever you happen to ask, even if they work there, could give you either answer depending on the day, because I believe so few people actually know or understand one way or the other.
