The Tron editing tools comes with documentation, and in it is a list of all the objects and what they do. Look for a file called "TRON Tools Documentation.chm".
Unfortunately, the documentation isn't that good and can be confusing. I've made a few video tutorials on how to make Tron 2.0 maps, which can be found here in the Tron-Sector file archive
Also, if you have any further questions about making maps for Tron 2.0, you can visit the LDSO site
forum and ask there. Most of the members there have experience with making maps.
