From what I hear there is no real difference anymore to have a belted or non-belted case. Some say non-belted feed better, and others say there is no problem with belted feeding properly. I personally would not care either way. I guess it is what you want.
As far as longer barrel goes, you really won't gain anything past 32" barrel. A caliber is specific to its purpose. The heavier magnums will benefit from a longer barrel due to the amount of powder that needs to be burned. You want to find an optimum length to burn all the powder before the bullet exits the barrel. Or you have to find a powder that will burn completely before the bullet exits. It is a trade off between length and the speed at which the powder will burn.
From the technical standpoint, you can add about 40 to 60 fps per inch, though that is not entirely true. You can read an article about this on the Lilja web site. They have some really good articles that address a lot of the long range issues.
