mondeo mk3 calipers can be picked up almost anywhere, probably best looking at a scrap yard for a pair even check some jags as they have same ones pads and discs easily bought anywhere, euro car parts do good deals on brembo brakes, and can sort you out a pair of hoses, you can also ask goodridge or similar to make you up a pair suited for the caliper and car as for wheels, everyone will say 16 inch wheels and bigger will do, however there are some 15 inch wheels that can fit over them they just need to be motorsport/lightweight types i think some team dynamics pro race 15's fit over them
