OK everyone, I got some answers!!

First, once you compile, the folder where you put the .jar files needs a copy of the lib folder, which contains the xml folder. That's all that is really needed to get the extra header capability. I have not determined if the QTJava.zip file is needed, but my guess is no.

Now there are a bunch of jar files that do not appear to do anything for running the compiled program. They are: ui.jar, sound.jar, MacStubs.jar (maybe only for mac?), and core.jar. However, do include the LimeWire20.dll so you won't get a startup error. It's only for the icon, but it will avoid the annoying message.

Please comment if you have anything to add.
