I know you can install 12.5mm drives on a MBP, but I don't think you can in the MB (don't quote me on that).
Currently, only WD & Toshiba offer 1TB 2.5" drives (WD=5200rpm, Toshiba=5400...have yet to see the Toshiba for sale in North America), but both are 12.5mm.
If in fact you can't install 12.5mm drives, 750gb is your next best option (again, made by WD & Toshiba)...both are 9.5".
edit - you may want to contact this person re: their experience...I could be wrong about the 12.5 not fitting:
