Why can rubber rubbed with wool attract small bits of paper?

The reason why the pieces of paper are neutral is that they contain equal amount of positive and negative charges and so they cancel each other out. When you bring a charged plastic comb to the pieces of paper, the charge opposite to that of the plastic comb will be brought to a part of the surface of the paper where the plastic comb is. Opposite charges attract each other, and since you're holding the comb, the pieces of paper will be attracted to the comb.

Why can they not use metal combs instead of plastic combs to attract pieces of paper?

Since the metal comb is a conductor, any charges you're able to place on it are conducted straight to your body as soon as you pick it up. So the comb never accumulates enough charge to exert much electrostatic force on the shreds of paper.
