Rem choked barrels uses screw-in chokes, so they are interchangeable, so you can use any choke you want (cylinder, improve cylinder, full etc.) as long it's a rem choke.
1. Extra full is appropriate.
2. Doesn't matter too much IMHO, you are so close that spread doesn't really matter.
3. More open one. What are you going use slugs for?
4. Sure, as long as you have rem choked barrel...Check out Briley chokes they are excellent.
The synthetic 18in barrel has a fixed cylinder choke so you can't change it, if you're going to hunt turkeys you need to get another barrel, either with a fixed full choke or a rem choke barrel. Or go with the turkey gun.
