You don't want to insulate the floor. If you want the floor to be warm you need to encapsulate the outside walls and condition the Crawlspace. If you have heat running to it in the winter your floors will be warm and if you have a/c in the summer it will keep moisture from building up. If you treat it as just another room in you house you shouldn't have any issues.
