TC is there to prevent the rear wheel from spinning, which is bad because it overcooks the tire and reduces acceleration. I think everyone in MotoGP uses it.
The anti-wheelie thing I've read is a launch control system (like the one they had in F1 in 2003), in the start procedure the rider will just completely release the clutch and the electronics will make sure maximum acceleration is obtained without stalling and without wheelies. I don't think the LC is used once the race is started.
