if you're concerned about honing the cylinders, take a bore mic and see if you get ANY difference. if not..new rings on Nikasil will seat just fine on the low milage engine you have described...just like wearing in a new engine...no worries there, the only thing I can think of that may cause issues would be if you didn't run it in "right" and you began to use a bit of oil. Just trying to ease the anxiety for you. Can I get a witness?
