Everyone seems to have a pet finish. I would advise against linseed oil, shellac and true oil. Anything sold by Chambers or Kibler will work fine.
I mostly use semi gloss spar varnish, diluted 50-50 with turpentine, and a dollop of japan dryer on maple. I have never finished pear, you may want to dilute it less if the wood is porous.
Finishing wood is 90% experience and technique. The exact product is not the most important thing.
Honey maple stain?? Staining wood is mostly cut and try. One particular stain is likely to not work, it depends on what you want. I imagine a stain called "honey" will look blond? I never saw a blond stock I liked, certainly not on a flintlock.
To each his own though, it is your gun. It only matters that it makes you happy.
