Welcome Jamie,
This is a perfect time to underscore a point about smoking sausages, seeing that Santa seems to have brought a lot of lucky people Bradleys this year.
What you are wishing to do is unsafe. You've bought fresh Johnsonville sausages and want to smoke them. Making smoked sausages is a bit more complicated than that, in that a cure would have needed to be introduced into the meat mixture prior to stuffing them. Cure ensures that the product can be safely smoked at the low temperatures required for making such sausages over the extended period of time in the temperature danger zone.
What you want to do (which is to cook the sausages) can be done safely on a traditional grill. If smoke flavoring is desired, a handful of wet chips works well.
But your ribs...now there's something you'll enjoy by firing up the Bradley. Share the recipe if they turn out good.
Best of luck.
