Personally I wouldnt bother with new rings or shells... but then I seem to get through shit quite quickly!... follow what folk have said and make sure you remove the carbon lip on the top of the bore with a bit of high grit before pushing them out, so you dont break any rings and as mark pointed out use alot of oil on re-insertion
space your ring gaps apart too...
