If it's sticking and dragging, that usually means the piston is corroded, which will need to be replaced.  It (they) can be professionally rebuilt, or buy two new calipers (it's always best to replace in pairs IMHO). Here is a rebuilder I've used several times for Vanagon and MGB calipers with excellent results: http://www.goldlinebrakes.com/

My right side brake caliper is dragging and making a scraping sound.  Should I just replace it or is the rebuild kit easy enough to do?

Thanks,
Bryan
