I plan on purchasing a wood insert. I have a 2 story colonial w/ attached 1 story garage. The chiminy (back of fireplace) is in the garage, then outside above garage roof. Is there any need to insulate liner? When I burn will the garage heat up?

Depending on the condition of the clay liner in the existing chimney, you may have to insulate to meet code either way.
If the garage is not conditioned space, insulation would help draft better by keeping the new liner you drop in warmer.
I have similar set up, cept my back of the chimney is now in my soon to be new bedroom, which at the moment has no heat. I can notice a very minor difference that while it does in now way heat the room, I can feel a very slight difference in temp while burning in the winter. Your most likely not going to notice much if any of a difference in the garage.

Unless you know for a fact that the chimney is up to NFPA 211, then you would want to insulate the liner to achieve the UL 1777 standard.
