Bnthrdntht, welcome to the forums!
If you have ANY questions about Android and how to do something, feel free to ask. Our whole purpose here is to help you MASTER your device... and then maybe go on to help others do the same. Have a question? We exist
to answer it.
iOS and Android do much the same thing, just in different ways. You can find a lot of customization options in Settings, and you can set up widgets (which are live feeds to your home screen instead of a static icon) and wallpapers by long-pressing a blank spot on the screen.
Hope this helps and again: your device-specific forum is a vast wealth of knowledge for you. We're here to help you
