Ah yes, the beauty of a quality shotgun. One of these days I will post a pic of my $16k competition Kreighoff.
Chris, originally there was a plastic bag with some stock spacers (probably 3) plus a steel washer (for lack of a better term) that has an off center hole in it. It will have some letters and numbers stamped on each side, as does the spacers. The black spacers are adjusters for stock drop and cast on/off and the metal piece goes inside the stock, a certain way. There will already be one in there now. They usually give you 2. All this stuff is for stock adjustment, in the event you need it. It may be close now, without doing anything to it. Shoot it a while and see what you think. Also put it on a patterning board. Ideally you want 50/50 or 60/40 for sporting clays. Don't use a rest when you pattern it. Free stand and mount the gun, point & fire without thinking too much about it or aiming too much. Take about 5 shots before you bother going up to look at your pattern (from 30 yds). When you do look at it, pay attention to the genreal masses of hits compared to your aim spot rather than the edges of a given shot.
Have some FUN brother!!!!
PS- I have one of those (391) that I got custom painted with 6 layers of metallic blue and purple splatter. Then tricked it out a bit with some crome pieces. I will have to post of pic of that one sometime also. I think RJCardema shot it when we met in Vegas a few years back.
