Gates, do a search on youtube "Crawlspace Insulation" and you can find some good information from companies such as Owen Corning, Johns Manville, and some private contractors. I was recently looking into this and I believe they recommended R-19 which you can double check on Owens Corning website.
There is also the question of if it's a vented crawl space or not a vented crawl space. Main difference here I learned is a vented crawl space does not get the walls insulated (although mine are from the previous owner) while non-vented crawl spaces you can insulate the walls with foam boards, batts, etc...If you lay batts between the floor joists, paper side usually goes toward the warm part of the house which would be your floor.
