Start reading the Litestep docs; not the third party modules.
It will give you clues about how Litestep start-up, what's the step.rc,... It'll give you the basics about configuration (in general) and will tell you about the basics modules (desktop, popup,...)
When you'll have a working popup, taskbar and systray (even if you don't like its style) you'll be able to go further by searching specific modules.
Good luck and be patient
