By using a current source the input bias current is independent of common mode input voltage.
By using a current source the operating voltage of the second stage is constant. This ensures that noise and bandwith is constant and don´t deend on common mode input voltage.
yes, changing common mode input voltage means changing voltage across emitter resistor, thus changing resistor current, changing emitter current, changing base current = input bias current
