Don't be afraid to make the adventure your own. What I mean is two-fold. First, don't worry about being wrong, especially if you haven't read ahead. Just roll with it when new information comes out. Secondly, the adventure path is fleshed out well, but not immutable. Change things when needed - add more that you party likes and connects to backstories, remove or modify things that they don't care for. The text is only guidelines, so have fun with it and make it your own.
