A smoothbore is cheaper and works just as well when using regular shot. A rifled shotgun barrel only helps if you are going to be firing slugs, but if you are it improves performance considerably, giving the slug near-rifle accuracy. If you can afford it and plan to be using slugs the rifled barrel can be well worth it and gives you much more versitility.
probably not, historicly shotguns are smoothbore if you shoot a slug, THAT would be rifled.
A shotgun is an example of a smoothbore. The inside of the barrel has no grooves cut into it, as a rifle would have.
Scattergun, smoothbore, fowling piece
Well there is no Remington Model 12 shotgun, a model 12 is a 22 lr, they did make a smoothbore but it would have said so. A smoothbore model 12 is rare and valuable but I doubt that's what you have if it doesn't say smoothbore it's probably shot out.
Yes. Rifled slugs are intended for smoothbore barrels (abot slugs aer for RIFLED barrels). Best accuracy with rifled slugs is USUALLY a modified choke, but can be safely fired thru any choke less than EXTRA full choke.

Yes. Exercise caution. Do not attempt with a full choke.
Focus on the target, ignore the barrels.
One or two, depending on how many barrels the shotgun has.
both barrels are not choked
AFAIK, no.
a shotgun is pump action and a revolver "revovles" the ammo.
