More than just documentation, what I would love to see is a set of tutorials or quick-start guides written at a roughly graduate-student level, that show a few examples of how to use all this code for common tasks. Perry and Robert's famous tutorial document (pydatatut.pdf) is an excellent start, but it's several years old now and misses all the new modules.  I know it's a long way off until we have, say, an actual text in data analysis that we can point students to, but I think it's very important to keep new users (and IDL switchers, etc!) in mind when writing docs, not just other python gurus.   

For the web community site, there are already a few potential candidates (astropython.org, astrobetter.com, etc). My experience with these sorts of things in the past is that it takes a critical mass to keep a web community active and engaging. Seems like half the wikis I know get very little usage... So while everyone is thinking about monolithic vs. distributed package organization, it's probably worth considering that same question as applied to web sites too.
