What you want to do is choose move roll them up into the first five icons. These will be the ones you see when you are on the home screen.

Well actually 6, not 5, with the stock Precision Zen theme.
If you have the original theme in use, the top row of your Icon Screen will be the bottom dock of your Home Screen. Move something else to the top row, it's now on the Home Screen bottom dock!
