I would insulate the subfloor, not the foundation walls.

Lefty is correct, but I also know that here in cold country sometimes you have to insulate the walls. In fact in many areas that is code. The easiest way is with foam board. 1" is best. Just cut to fit and set against the walls. Will stay there forever. However not alot of R value. The batts in plastic are really good, and you can get cold weather tape and tape them up. I just did a job in very cold part of the country where we pumped the crawl space full of cellulose. Boy am I going to here feed back on this one, but it worked terrific.
