yes, you should read them! as a teenager, I know that the Catcher in the Rye was a really fast, very moving, and deeply disturbed piece of fiction. Alas, I also cannot give an opinion on The Bell Jar (I am reading it after I finish my current book!) but I have heard people say that it is the female version of Cather in the Rye. You'll love it. and if you don't, it's a very quick read (took me only two days and was taking my SAT test on one of them so that should show you how riviting the story is). but you'll end up loving it, trust me.
happy reading!
