The HD is hidden by default. You can make it visible by going to:
Finder>Preferences>Show these items on the Desktop
Put a check mark in the square next to
Hard Disks to make it desktop visible.
To learn how to use your MBP, read the manual/booklet that came w/the comp.
Also check out the OS Help Menu.
Two non geeky easy reading books that are very helpful:
Macbook for Dummies
Mac OS X Leopard: The Missing Manual
