How do I created desktop icons and annd new quick launchitems?

There should be a shortcuts folder in your litestep directory, try placing shortcuts in there and then recycling.

it all depends on the theme. if the theme you're using already has desktop icons and quick launch, then follow goats advice. if not, then you'll need to download and configure a desktop icon module. same thing for quick launch.
also, when you're naming a thread, why don't you try using something at least SOMEWHAT descriptive? "total newbie" usually tells us that the person hasn't read anything on litestep (which we don't like very much!).
