The default look of Ubuntu can sometimes be a bit off-putting for a new user who is used to the flashy looks of OSX and Vista. And to customise the look of Ubuntu from boot to desktop can be a daunting task for new users.
From boot time there are three main themes that you see until you arrive at your desktop. Grub, Usplash and GDM themes. These themes are machine specific not user specific. That means that it affects all users, but only until their desktop is displayed. Then they will not see these two themes again until they log out or shutdown.
For user specific (desktop) themes the main components that govern you look are GTK2 engines and themes, Metacity, Icons, Wallpaper, Fonts and Splash Screen images.
