First one - sort the rust out. Don't worry about the wiring "loom", the cable bundles through the main body of the car are just pvc taped together. That was a bit of a surprise for me....
Edit: where is the first one taken?
you need a jubilee clip to secure the big pipe to the air filter box ASAP as at the moment your punto is sucking in unfiltered air. You also need a new breather pipe as mentioned. Both are cheap and both available from fiat. As I say though, you need to get the main large pipe secured to the filter box asap.
