I also bought Goodridge hoses and Halfords 5.1 fluid separately.
This included everything I needed.
The only complaint I've got is the dust from the stock pads, but you're going a different route so not really applicable.
I chose stock pads first, so if / when I go aftermarket I can gauge any difference.
