I thank each of you for your thoughtful responses, s2photo in particular. The advice on chokes is something I would never have thought of and the idea of me and my wife being able to shoot the same gun well is something I should have thought of and didn't. It is encouraging to hear that we can start off on the cheap and still be in the game.
I will caution you that you will both be able to use the gun if you are of relatively the same build... Shotgun manufactures build for the Average shooter, those of us who fall outside of that "normal" size will benefit from some stock fitting. Myself - I'm 6'6" the LOP (length of pull) on my shotgun had to be lengthened quite a bit, and the drop increased slightly to accommodate a longer neck.
But until you start shooting and get a sense of how to properly mount the gun - not much of this will matter. Its a catch 22, you'll shoot best with a well fitted gun, but you can't truly be fitted until you've done some shooting. You could try to find a stock fitter with a "try-gun" (which is a fancy rather adjustable gun) to get your ideal measurements; However in Canada they're about as common as a unicorn.
The advice of finding a coach of some sort, or at least talking to some of the well seasoned shotgunners at a club is great advise. Most guys are pretty friendly at the clubs and most will help you out or even let you try their gun for a few shells.
So once again, best of luck, and have a blast.
Oh also, your wife and you (if you fit well enough) can share the same gun, but some clubs will either frown upon sharing the gun in a squad, or have a rule against it (for safety/consideration of others time) Best to check with your local club first. You can always take turns however.
