Where exactly should we be looking for the documentation for exo kernel?

The documentation of the kernel is shipped with the documentation of eXo JCR that you can find here http://jboss.org/exojcr/documentation.html

I know there is some in the reference guide, but there is also
documentation on the exoplatform wiki.

The doc of the latest version of the kernel is indeed in the reference guide of eXo JCR (http://docs.jboss.org/exojcr/1.12.3-GA/reference/en-US/html/part-kernel.html). The wiki was needed before we ported the whole doc into docbook, since now we ported everything, the official and unique doc is the reference guide.

All I want to be able to do is to access a service in the portal during
the deployment of an application. But configuration.xml files only
appear to be used when the server is first started, and if I access the
kernel directly in java (ie PortalContainer.getInstance) there doesn't
appear to be any way to guarantee that the dependent service is running
yet.

In eXo JCR, the components are first initialized i.e the instances are created following the dependency order (remember that components are injected by constructor) then the components that implement the interface org.picocontainer.Startable will be started following the dependency order.

In your case, what is your component? when do you want interact with it (before creating it, after it has been created, before it is started -if it implements Startable- or after it is started)?
