You don't NEED to do your rings. I did though when I did my head job. To do it right though you'd need to replace more than just the rings.
rod bearings
pistons and rods need to be checked by machine shop
they need to be checked for ovaling
crank bearings would be a good idea

Yeah i'd pull the balance shaft for sure it lets the engne rev way faster. It idles a little lumpy but not to bad, to get the white deposits off the valves i used a bench grined with a wire wheel. Of course they have to be out of the head to do this, but i'm sure you have them out anyway.
