How do insulate the outside of a log home?

I built a dove tailed, flat inside and outside, chinked log home with 10" thick by average 18" long red pine logs.  I heat it mostly with a masonry wood stove, backed up by an electric boiler. it's built on a slab with radiant hot water heating. I want to increase the efficiency of the house by insulating the outside. What I have in mind is vertical 2x4 strapping, 3 1/2" Roxul insulation, horizontal strapping with 1x3s and then either vinyl siding or pre painted wood board and batten. My questions would be, do I need to have a air gap between the logs and insulation and should I use a house wrap over the insulation. Any advice would be most welcomed. Thanks
