Answer #2. The prefferred method is 2-2-1 with Baby Backs as they are smaller, I believe. If you go 230°, then you might want to try 1.5-1.5-1 as that is 5° over the low / slow 225°. But the standard is 2-2-1 so you can play with the time to see what suits you better. Check for pull back, doneness, use a thermo to probe but don't hit the bone. Play with it & have fun. Good luck.
None of the questions that you ever ask here are dumb. You are just un-informed until you become informed.
They are known as baby back ribs. I would also use the 2-2-1 method the first couple of times to see how you like them. Then if you need to make any adjuments then you will have a basis to change things.
