I want to remove the whole "bar" on the bottom of the home screen where the Favorite and shutdown Buttons are placed on (in order to see the whole Background)

You'll have to modify the skin. Look in IncludesBackgroundBuilding.xml. Around line 73 there is an include group called ContentPanelBackgrounds. The first image control has a texture called floor.png. If you remove that image control, then the floor will be gone. The catch is that it will gone from everywhere, not just the home screen. If you want it gone from just the home screen, you'll have to add a visible condition that evaluates to false when the home screen is active. I'm not sure exactly what you need to test for, but hopefully that'll get you started.
