1. Not really gear-related, but more security-related. Your deadbolt locks - assuming brand new house with others nearby still being built - are still accessible with other "master" keys held by contractors, sales agents, realtors, etc. until you follow the instructions on the key envelope. Something like inset key, turn left, then right two times, then left again, then put your right foot in and put your right foot...sorry, but you get the idea.
2. On your map of the area, figure out where important things are like the nearest police station, fire station, hospital, and Home-Depot (you'll be there alot!).
