Frequently there will be shims in the box with the starter. You measure the clearance between the starter shaft and ring gear to determine which shim or if a shim is needed at all.
Yes, changing the ring gear is pretty involved. You will have to get the trans, bellhousing, etc. out of the way so you can remove the flywheel/flexplate.
It is easy to check the teeth on the ring gear by pulling the starter and looking at or feeling the teeth inside the hole where the nose of the starter goes.
