Hi there 071's will be fine very good plug for the money, quite widley used and reccomended by some top people as a good budget plug. As for a group A coil, I fitted one before I changed to wasted spark, cant say I noticed much difference either positive or negative but having said that I didnt have any problems with the std coil, as for plug leads the std beru leads are very good as long as there ok, if not I would go for the ford motorsport leads, available from lots of places, inc matt lewis msd etc.
