You're going to have to read a lot more than that, my friend.
However, for the record, as another of those ex-YEC's, "On the Origin of Species" is a powerful, powerful book. Admittedly, I was already converted to evolution when I read it, but it gave me a perspective I'd never heard on any internet debate board or in any other book.
Nowadays, with all the info we have, most papers on evolution begin with the past and work toward the present. Darwin begins with the present and works toward the past. In doing so, he makes all the debates about radiometric dating and gaps in the fossil record irrelevant. He fills the world around us with missing links and passes on information so fascinating that it feels terrible not to be able to repeat it.
It's still my favorite book on evolution, and, in my opinion, the most convincing one out.
Not to dismiss anything you or Crash said. Obviously we've come a long way since 1859, and "Origin of Species" won't catch you up on biology. But what a great book! And I don't think Gould or Dawkins are as convincing as Darwin. He did write his book to convince creationists, after all.
