Easy Mode - go ahead and clean up your icons move your pr0n folder from the desktop, close your tabs etc.
Medium mode - Only get rid of your minimized windows
Hard Mode - Turn off Autohide on all docks and toolbars, don't delete desktop files leave minimized windows on your toolbar.
I for one went with hard mode.
I never have icons on my desktop if you are suspicious. I can't stand anything on my desktop that's why everything autohides. I don't know the actual reason, I even delete minimized windows the second they hit my notification area...
