James Spencer over at Basicbrewing.com has done a few all-wheat beers. If you do BIAB you won't have to worry about sparge issues.
There's a great video detailing it here:

So, I emailed James Spencer about this video because they seemed to like their beer and I thought, I'll try their method first before experimenting. Here's the important stuff on their all wheat beer.
He wouldn't do an all-wheat beer unless it was BIAB.
Mash at 152-154, but he mashes all his beers that way (although in the above video it seems he does a step mash and decoction).
Sparge at 170.
He says it will work with step mash, single infusion and decoction. Sounds like he does his single infusion. No protein rest although I asked in another email tonight. I will let you all know what he says.
I may be attempting this beer this coming friday and here's what I think I may do. I might make some fine adjustments come friday morning.
20 lbs white or german wheat depending on what's available at the LHBS and I will beg them to change the gap to crush as fine as possible.
BIAB full volume mash 10.5-11.5 gallons water
Protein rest at 120 (not sure if I will, wheat beers are supposed to be cloudy right?)
Mash temp 153
Mashout at 168-170 (Is it really necessary if I'm getting higher efficiency from a finer crush and avoiding the stuck sparge by squeezing the bag?)
1 hour full boil to get 10-10.5 gallons. Ferment will be in two 6 gallon carboys and I'm going to do a secondary with 5-6 lbs of watermelon in one and nothing in the other.
Haven't decided on the hops and or yeast yet but....here is what I want:
more citrusy, less bitter beer and a fruity, estery after-taste (Isn't that what most people want in a wheat beer?). I'm thinking a first go would be a german hefe yeast and then on the second go (next beer) an american yeast just to see what the differences are. I'll let you guys know how it goes and when it's done I'll let you guys know how it tastes as there isn't much out there, or even on here. l8r.
