If you are a guy, just tell him. If you are a woman and you know him well, just tell him. If you are a woman and you don't know him or are just acquaintances, ask a man to tell him. It's less embarrassing for him that way.

Time to blow your mind. It's not a flea at all. You're thinking of a fly. However, it's not that either. The zipper is called the zipper. The fly, is actually that little flap that covers the zipper. So when someone says, "You're fly is down," it's not. Your zipper is down. Your fly can only be open.

The part of the zipper that comes up and down, and opens or closes the teeth is called the slide. It usually has a zipper pull attached to it which is a tab to help it go up and down. Sometimes the tab breaks off, but a new one can be attached. For more about the zipper and how it works, see this: http://science.howstuffworks.com/zipper.htm/printable
Yes, when inserting a zipper, the zipper should be basted in first (to stabalize it while it's sewn in). When basting the zipper, it should be basted to only the seam allowance.
