Our Pack requires from the belt and up. We provide new handbook and necker at our May graduation. BSA says that uniforms must be "official BSA", but it doesn't require that they be current issue or color cordinated.
With a Pack of about 80 boys, the colored neckers do help and they are cheap. When my oldest son moved on to Boy Scouts, the old cub neckers where added to his first-aid kit.
As for the hat, that does bug me given the price for something he'll wear about 15-20 times. I have been thinking about proposing to the committee that we use the Wolf hat for all Tigers-Bears: it's the official Cub Scout colors.
My 2 cents - feel free to give me change back...
