I would start out with this website.

This was put together by a long time shooter and helped me very much when I started. My picks for a first time shooter would be Ruger Blackhawks or Vaqueros (adj. sights or no adj.sights) in 357/38 for pistols. a 1892 clone or Marlin 1894 also in 357/38. And a Stoeger coach gun or IAC 1897 clone pump gun for your shotgun. Check out the website their are plenty of choices.
Have fun and welcome to CAS !
