Congrats on your successful bear hunt!
I do not have any experience with bear meat. So, you have to cook the meat to an internal temp of 160 huh? Smoking/Cooking the roasts whole is tricky at best if you have to take them to 160 which is way higher than I would want to take a beef roast or loin.
For your ground breakfast sausage, you could make a "Fatty" (search for Fatty in the Sausage section). I haven't made one of these yet, but it is definitely on my to-do list and seems pretty easy and looks like it would taste awesome.
You could definitely make some jerky from some of your roasts. That is what I do with a lot of my deer roasts and it turns out awesome.
You could also grind the roasts and mix with some pork and make some snack sticks. I have several posts on making snack sticks in the Sausage and What's Cooking sections that may help you.
I hunt/smoke a lot of venison, Pheasant, Duck, and Goose. But, as I mentioned earlier, I do not have any experience with bear meat. So, others with more bear and/or large wild game meat experience may have some better ideas for you. But, I think my ideas above could work for some of your meat.
