    Why is that when writing the bits for down counting, you move from 111 to 000 and not 111 to 110 as indicated in the state diagram

      You have to not Down move blindly. You have to look in the state diagram you have made and only as per that you have to move to the next state. According to the State table for 000 the next state is 111. For 001 the next state is 000. For 010 the next state is 001. For 011 next state is 101. For 100 next state is 011. For 101 next state is 100. For 110 next state is 101. For 111 the next state is 110. like wise you move down

      If you see properly 000 output is 001 and 111 output is 111 when M=0 is up counter. (0 to 7)
      Whereas 000 outputs is 111 and 111 output is 001 when M=1 is down counter (7 to 0)

      D flip flop is a Data flip flop. Output follows the input which can be made by JK or SK by connecting a NOT gate.
      T flip flop is a Toggle flip flop. It toggles the output when T= 1 or memory state when 0. This can be made by JK by shorting both the terminals.
