Playing live for the first time.

In about a week and a half I'll be playing live with my band for the first time.  We're a folky acousticy kind of band and we'll be playing at a local pub.  We've got all the live musical gear we need, monitors, PA, etc, but I'm pretty nervous.  I keep thinking I'm going to mess up and ruin it for everyone else. Can any performers out there give me any tips on how to avoid nerves?

I'm thinking about writing a song today.  I've got a guitar, some tin whistles, a keyboard, a melodica and a harmonica to play about with, but no idea what I could make the song about.  I'm open to suggestions from anyone.

Also in the plan for today is to finish off a silver chainmaille bracelet I started yesterday.  I'm trying to decide how much I should charge for it, so I may put up a picture later and see what you guys think.
