Sometime this weekend I'll be getting a black 3g 8GB iPhone, and I'm super excited!!

What are the most important things you guys can suggest that I do to get the most out of this device?
Battery managment (following a charging guide for new iPhone)?
Some kind of insurance (squaretrade or statefarm)?
Some kind of invis-a-shield or body guardz?
What apps are a must?
Should I load apps sparingly or go for it?
Etc....
Any suggestions that you have or things that you would have done differently would be great!
