I'd drop your crystal 30 to about 1/2 lb.
For the hops you could decrease each addition by about 20% and benefit your beer. Another approach would be to drop the Amarillo bittering addition since that addition will boil off most of the great citrusy character of the amarillo. You could then make the 45min simcoe addition your 60min bittering addition. Might also drop the 1/2oz of warrior at 30 too. That'll bring your bittering efforts down out of the pliny range and give you fewer grass cuttings to try to whirlpool out. Hopping is very individual so its all in whether you're looking to meet an IPA style or just make a beer that meets your needs. Might look at Ray Daniels Designing Great Beers. He talks about BUGU ratios. I have found this guideline for keeping bitterness balanced with gravity relative to the style you're trying to brew very helpful when pulling together recipes.
If you do not already have brewing software, you might go to hopville.com and use their free online recipe builder. This allows you to plug in your ingredient list and then tweak them up and down and see how it'll impact your gravity and bitterness. Not perfect, but it gets you in the ballpark...and free is nice.
