if you want originality, you can buy the proper green brake pipe from fords still! (you will need a small bending tool to bend it though as unlike the copper stuff from motorfactors it will kink)
all the fittings are available from any decent motorfactors

As for braided pipe, yes, its better than the rubber hoses ford supply, however it will never be as good as solid piping so only flex up, what should be flexi on the brake lines

as for fuel lines , exactly the same as brake pipe, except it don't matter if its all braided
