I was also going to chime in on the need for hearing and eye protection, even a "little" .22 creates noise enough to damage hearing, and once it's gone, it's gone. I've always worn glasses, but I've lost count of how many times something has smacked into a lens that would have injured an eye.
Next; get a decent cleaning kit, but go EASY on the bore on a .22. Way more .22s have been "cleaned to death" then shot out. Save your next old toothbrush, buy a bore snake, some Hoppes and Q-Tips, and and old T-shirt.
