The wheels that come on your bike may work out just fine. Don't think about replacing them before you need to.
Tire pressure ratings are very rough. A few years ago, I read that manufacturers test their tires at double the rating. Overinflating your tires will protect your wheels from the forces of a heavy rider. Try 100 or 110 psi in the rear tire and a little less in the front. You are not likely to have a blowout from this.
Welcome to cycling! Many people have improved their health a lot in a fairly short time, and it's very rewarding, too.
