I love a touch of fresh ginger in my wits (I handle all my brewing spices with a very light touch). Chamomile, coriander, fresh orange and grapefruit zest, black pepper and even cumin have all meandered into the recipe from time to time. My lesson from last year's 10 gallon all grain batch of wit (brewed with WLP400) is let that yeast get warm. I fermented it at the coolest end of it's temp range (not sure off hand but it I recall it was the coolest temp recommended by White Labs) and the yeast was not nearly as expressive as it has been for me in years past. I let it rip at room temperature once before and following a month of conditioning in the keg it was a far superior product to the cool fermented stuff. I'm not espousing letting this stuff ferment above 85 intentionally, I'm just saying that I prefer this yeast on the warmer end of the spectrum.
I personally don't bother with the protein rest. For what it's worth: I do a single infusion at 149 with a very tight mill (89% efficiency), I mill my flaked wheat, I skip the rice hulls entirely, I fly sparge and I don't get stuck sparges. You've got 2 pounds of rice hulls, you'll be fine. I'd mash long and low to ensure full conversion of all that flaked adjunct/munich malt, and be sure to do a solid boil to drive off that pils DMS.
