The disk usage should be easy.
Your OS should have tools for recursively measuring the directory structure of your app.
Memory is another story.
There's heap memory, permgen, etc..
They all, of course, will vary according the load on your system.
Java 5 ships with the jConsole app which does a nice job of displaying memory usage in graphs.
The Server Status page in the Tomcat Manager app will show you your current, max, and available heap space.

Tomcat manager is highly recommended. In addition to memory it will show you the status of the Thread pool and request statistics. Very handy for spotting potential bugs.
It is sorta covered in the
