FWH is first wort hops... added to your runnings in your kettle and steeped there before you boil.
In terms of your grain bill I would do away with the CaraPils. Instead use a light crystal between 10-40 for some flavor and color. CaraPils won't add any thickness to your beer. It will only add to your head formation and retention, but so would a darker caramel or crystal malt. CaraPils is effectively something like Crystal/Caramel 0. You can get the same benefits to head by using a darker crystal and add some flavor and color to your beer. I would also up your 2-row by 1 to 2 pounds. IPAs land in the 5-7% abv range. This might wind up as an APA depending on your efficiency.
As for the hop schedule, it really depends what you want in terms of character. If you like a forceful, upfront bitterness, chinook at 60 is a good idea. If you prefer a more subdued bitterness with a bigger flavor, get to about 40 IBUs with an addition between 60-45 minutes then through about 4 ounces of whatever in to the kettle in the last 15 minutes. You will need to use more to acheive a higher IBU but you will maintain more of the flavor and get a well rounded hop profile instead of a bitter hop resin. Also, up the dry hop to 2 oz. minimum for about a week. 1 oz will get you the aroma, but it won't last long. 2 oz. at a week has worked well for me. You could even get creative and do 1 oz for 5 days then pull those hops out and throw another ounce in for another 5 days so that it wont be sitting on old hops for 2 weeks.
Lastly, what are you mashing at. If you want a solid malt body to back up some heavy hopping, the 152-154 range is nice. If you like them dry and bitter 149-151 will do you well. Upwards of 155 you will probably have to much lingering sweetness.
