Congratulations! Okay, get a copy of "What to expect while you are expecting", great book. I second going to all the doctor visits you can, really a cool thing. Don't count on using a camcorder during the delivery, most hospitals do not allow this for liability reasons. Once the baby arrives, tell your wife to sleep whenever the baby sleeps, trust us on this one.
Most importantly, enjoy that kid, they grow up way too quickly.
