| Two way or one way is not going to have any effect on the trunk group if you are using it for incoming only. CBC means that you are allowing the call to determine the service you are using if you have several choices, also not really a factor when you are only receiving calls on this span.
I would probably have chosen public-ntwrk as the service type myself. If these are AT&T 800 numbers, you might have been able to choose mega800. If these are International 800 calls, then possibly i800 would be a choice. There is really no one best answer, that's why there are so many choices.
However, the basic guideline should be, if it is not broken then don't fix it. __________________
