You only need to remove vlan 8 from the prune eligible list on sw1 port fa0/13 to solve problem 1 (switchport trunk pruning vlan remove 8). Problem 2 is already solved by the vtp pruning that you enbaled on both switches. You do not need to play with the vtp allowed list to solve these 2 problems. Test it out.
