Get some band-aids for whatever you shoot with it because it will probably break the skin.
I'd go .40 cal or even .45 if you like putting big holes in things.

Make sure you get eye and ear protection....spend a bit more for better stuff if you plan to shoot a lot. You get what you pay for here. Also a run of the mill cleaning kit available at the gun store will do just fine.
Hard case and you should be good to go.
