What is the difference between Node "core" and "userland" modules

https://github.com/ry/node/wiki/node-core-vs-userland

What is the versioning scheme?

Odd versions are unstable, even versions are stable. v0.2 and v0.4 are even/stable. v0.3 is odd/unstable. The next unstable release will be v0.5. The stable branch takes bug fixes only - it does not change the JavaScript API, addon API, nor ABI (you don't have to rebuild modules after upgrading node with-in a stable branch).

What's the capitalization of Node.js?

The official name of Node is "Node". The unofficial name is "Node.js" to disambiguate it from other nodes.
