My advice: drop down the Crystal malt unless you like your pales to finish pretty sweet. For a 3 gallon batch I'd probably stick to around maybe 8 oz or so. It may not fall within the BJCP color guidelines, but who cares, it'll still taste good.
Also, for hops, Amarillo and Simcoe is a great combo. That said, I wouldn't waste any of their deliciousness in anything but the last 15 minutes of the boil. I like a 60-15-5-0 hopping schedule for my (I)PAs, with a cheap neutral bittering hop at 60, such as Magnum or Warrior.
