A few questions Coasting,Overdrive button,Air intake

I have a 2000 Mazda 626 LX

Is it safe to coast with an automatic car? or this only applies to standard cars? Is it safe to put my car in neutral down a hill then put it in drive?

What exactly is the overdrive button for? Should I be using overdrive for around town like I have heard?

Also do those air intakes like injen and akimoto/Conical air filter systems safe on gas?
