First of all, congratulations on picking such a good piece of kit.
Choke markings do vary a bit but the basics are as follows:-
SK/IIIII = SKEET for close range targets, out to around 25/30 yards if the clay is face on or side on if closer.
IC/IIII = IMPROVED CYLINDER OR 1/4 CHOKE for targets out to about 40ish yds. face on or side on (flat) to 30ish yds.
M/III = MODIFIED OR HALF CHOKE, for targets out to about 50/60 yds face on or 40/50ish yds side on,(flat).
IM/II = IMPROVED MODIFIED OR 3/4 CHOKE, for targets out to around 60/70ish yds face on or 50/60ish side on(flat).
F/I = FULL CHOKE. For targets out to 70/80ish yds face on or 60/65ish yds side on, (flat). but will kill out a lot further in the hands of a good shot.
I`v seen rising teal clays shot at 110 yds and nice clean breaks.
These distances are not that accurate as guns vary slightly as do cartridges. Plastic wads tend to keep the shot pattern together a while longer, so you don`t need quite so much choke. In general if you use a 1/2 choke to kill a bird cleanly with felt wads, then with plastic wads you can roughly, kill the same bird with a 1/4 choke.
Put the most open choke into the bottom barrel, that's one dot on your barrel selector. Then put the tightest choke in the top barrel, that's two dots on the selector.
If you have a close bird/clay to shoot first put the selector on bottom barrel/one dot.
If you have a side on or distance target first, then use the top barrel/two dots. This will help you out of a lot of difficult situations.

Need a complete description of ALL marks
there is a problem with the automatic choke
Probably $600 - $1500 depending on the model and assuming it's a field grade gun. If it's an older model without screw-in chokes, it would probably be around $600-$1000, the newer models with screw-in chokes would be worth more.
Value if in new condition with both chokes that came with it and the choke removal tool. Id say 750.00...New condition to me is that its NEVER been fired.
Individual or team that chokes under pressure.
Well it depends on the condition but anywhere from 650.00 to 750.00. They are coming down in value due to the fact that they are fixed chokes and would cost an extra 500.00 to get them bored out.
You did not say which Beretta/CZ you are asking about. If you mean which is the oldest company, Beretta lays claim to being the oldest operating firearms maker in the world. Go to their website, click on company history.
If you mean "military", it is the Beretta 92.
How much the shot is constricted as it leaves the barrel.
