About the last position:
Isn't quite easy for white to win. What if first white move his rook to a8. Black moves his king back and forward between h8 and h7. Meanwhile white moves his king to d7. Afterwards he sacrifices his rook for the bishop. white can force black away from the f7-pawn. White should be ware of stalemate but he wins if plays careful I am convinced.
