Did you pull the recipe online? Palmer's online recipes are designed for extract partial boils with all extract up front. In his book, he adjusts them for late extract addition and all-grain (similar boil gravities for both).
So the online recipes will be too hoppy if you're not doing a concentrated boil.
EDIT: If I had the book on hand, I could post the hop schedule from that. Maybe someone else can.
