Trapper, a lot of that depends on the rider, and the type riding he or she may do. The swap is easy enough to do if you wanted to change sprockets though. It does require several different hand tools, and the sprocket nut needs to be tightend to 83ft-lbs of torque. So I would suggest changing it out before you get ready to ride.
md2, I loosend the chain up all the way which made the removal and installation of the sprocket very easy.
