Yes it's all about the shaders. It took me about 3 months intensive
study to learn how to write my own shaders, but once that's been
achieved it's easy to understand why Pixar's (and all the others who use
renderman) movies look so amazing. In truth it's not really that hard to
learn if you have a good grasp of math, a bit of programming and a lot
of patience...

your own shaders or change existing ones.
yes... and some 'simple' things like environment based reflection maps
can be tricky to get going - for one thing 3Delight uses a different
type of environment map that any other renderer I've used. had me
baffled for ages.
In the renderman world there is a severe lack of easy to reach
resources. feels a bit like a special club sometimes. I think because
people end up putting so much of their own effort into developing even
the basics (there's very little ready to go material and even fewer
tutorials) that they are then very reluctant to share their results.
which of course only compounds the problem.
