> Shell out some cash on books by Matt Butcher / Packit Publishing. The Packit books are fine as far as they go, but are usually short and basic. For a detailed look at Drupal's big picture, I highly recommend Pro Drupal Development, 2nd ed. by John VanDyk. 2nd ed. is for D6, but I see that a 3rd edition for D7 is due out in April.
