nope that brake wont fit, think about it, look at the pista fork, there is a single hole in the centre so you need a brake that uses a single bolt fixing (not trying to be patronising)
search shimano 105 caliper - that's a decent cheap brake that you wont need to replace in a long time.
then you need to buy brake cable inner and outer, so the wire and the tube that covers the wire.
as for a lever there are too many to choose from to recommend really, a dia compe dirty harry is popular though.
