ANSWER OF SECOND QUESTION:-
IT IS a  misconception is that when rolling, there is a tendency for friction to act in the same direction as the tendency for motion of the center of mass. at a given instant during rolling , the point at instantaneous contact with the ground is at rest. so friction acts in the opposite direction too. this should answer the question no 2  , ie.
 
 when there is no slipping, friction acts along south  for both.

hc verma himself explained in an online lecture
also there was a question in fiitjee on this
assuming the cycle is a RWD cycle [general] friction acts on fwd direction for rear tyre and backwrds for the frnt one
