From the pictures it looks good.
In refurbishing an old firearm, the sky is the limit on just how far one wants to go. Touching up blemishes on the metal and keeping it oiled will probably be sufficient for a working shotgun. A wood stock will require a finish that keeps it sealed. Moisture is not good for wood. As long as you used a good sealer, you should be OK.
One place I've seen that gets neglected is under the butt plate. Be sure to seal that area well.
That ole' bolt action should do well and be fun at the same time. I still make it a point to take the bolt shotguns out at least a couple times each squirrel season.
Congratulations and have fun!
