Your expression for the velocity looks right; but we have to get a few other things taken care of. First - the center of the marble doesn''t move from 0 to 2R, it moves from r to 2R-r - so the potential energy due to this is smaller than mg(2R) which is what you had in your expression.. On the other hand, you need to take account of the energy of the sphere rolling (which is stated explicitly).
