Ye thats a zetec s kit, it pretty much bolts straight on, but you have to shave a little around under the front lights. Have a look on ebay as there are always plenty of zetec s fiestas breaking, so getting a kit should be a piece of piss. As for what else? depends on your budget, can you afford to stick a puma lump in it? (pretty straightfoward), lowering helps, (40mm spring and damper kit, or coilvers if you can afford them), and decwent brakes are always a good move, pretty sure you can get mondeo V6 calipers with 280mm discs on there farily easily.
