Yes I have check into the wheels, they are the same as the GSXR750 (25mm front, 28mm read axel size).
I went with TecnoMagnesio SuperLight on my 1100 last year, I'm just moving them to the busa (6.3lb front, 8.9 lb rear). Right now I am planning on keeping the stock rotors & calipers, but will change at a later date. I am going up 2-3 teeth on the rear sprocket (vortex), may change the chain.
