I think you will want to create a new one and then in the methods you need to call the super if it doesn't match yours. IE

@Override
public ICapabilityProvider initCapabilities(ItemStack stack, NBTTagCompound nbt) {
	ICapabilityProvider superProvider = super.initCapabilities(stack, nbt);
	return new ICapabilityProvider() {

		@Override
		public boolean hasCapability(Capability<?> capability, EnumFacing facing) {
			return capability == yourCapability ? true : superProvider.hasCapability(capability, facing);
		}

		@Override
		public <T> T getCapability(Capability<T> capability, EnumFacing facing) {
			return capability == yourCapability ? yourCapability : superProvider.getCapability(capability, facing);
		}
	};
}

I don't see how you could incorporate facing into an Item, but...ehh.

Yes you will have to create your own capability. The forge documentation is a little low, but there are examples out there Choonster has some example on his github. There is also this which helped me understand what I need for a capability specifically.
