I made a cherry saison and a cherry bock last year. I went too heavy on the cherry in both so start light on the fruit. 1 lb of fruit (including the pits) per gallon of beer is plenty for my taste. I didn't pit the cherries. They fall to the bottom when the ferment is done. The cherries will float while the ferment is going. Then, they turn lighter in color and fall to the bottom as a sludge/skin layer. You might want to bag them. I didn't, and had to put a hop bag over a stainless steel scrubby on the end of my racking cane. Otherwise, the cherry skins all gather around the cane tip and pug it up.
To clean up the cherries, I added some 10% Phosphoric acid to some RO water to get it done to 3.2 pH, then added 50 ppm potassium metabisulfite. I soaked the cherries in this bath for an hour then drained it. I understand that heating them can set the fruit pectin and add haze, but that might not be a problem for a wheat beer.
