A ground vapor barrier and insulating the WALLS of the crawl space with rigid foam to a code-minimum R15, caulking & insulating the band joists & foundation sill of the crawlspace, then removing the subfloor batts between the joist is really the right way to go, but if there's no hatch big enough to get sheets of foam-board in there it may have to be a couple inches of closed cell polyurethane instead.
