malt bill looks good, though I would use C-15L or C-20L.
good amount of sugar, too.
you need a LOT more hops. the varietals are nice choices, but I would increase them dramatically. at least double, if not 2.5x the late and whirlpool additions, and shoot for 100+ IBUs at the bittering (don't worry about the calculated IBU number - its bogus over 100 anyway, and the best commercial IIPA clones like Pliny, Heady, etc. often calculate in the 200-300+ range).
Also, you have no dryhopping listed, which, in my opinion is a MUST for IIPA. I would take the same hops you used in your whirlpool and use about 4oz or more for dryhopping, maybe in two stages (3oz for 7 days, 2 oz for 3 days, whatever).
looks very promising - I bet it will be killer!
