That's not a problem - I was not either when I started doing it. And
there are still a lot of areas I am not familiar with. There is no
need to know everything about numpy to do a good job.

One thing you could start doing is trying to make the mac os x dmg
from the paver script, and familiarize yourself with virtualenv if you
don't know it (I use virtualenv to install numpy in a temporary
directory before building the doc - this guarantees that the doc
matches the exact same version of numpy as the one you are packaging).
I spent some time cleaning the paver script before the 1.4.0 release,
so it should hopefully be readable.
