I am not a huge fan of cluster hops and would probably either go with a neutral bittering addition like magnum or even some earthy English hops to complement the pumpkin. I also don't think you need any flavor hops either as you want the pumpkin and spices to shine.
The grain bill looks good to me. Just be prepared for a messy mash with a potential stuck sparge from all that pumpkin. i have boiled mine in the past with good success and more ease. I just used a large 5 gallon mesh strain bag.

The last thing you might want to consider is to use a different yeast. Cal ale yeast will be very clean while using an English ale strain can lend a maltier body with some more interesting fermentation aromatics. Just some food for thought...

Maybe I will bitter with the hallertau. The 20 lb pumpkin is the weight of the actual pumpkin approx. so I may only have 10 lbs of meat going into the mash. I am hoping the rice hulls will assist and keep from a stuck sparge.

Change of plans. I am going to swap out the pumpkin for sweet potatoes 8-10 lbs roasted and back the spice down from 4 tbs. to 3.
