http://Www.etis.ford.com for detailed info on your van.
Not sure what if you would have the loom for front fogs until you look underneath the van.
Being a 57plate it's most likely a mk1 facelift. The original mk 1 had "square boobs" on the front bumper, the facelift has a smooth front bumper.
Servicing wise, stick with fords (if you're rich) or go with Delphi or bosch filters. I've always used them and never had a problem.
My van came with one key (with glass transponder chip in a blue compartment) and a seperate fob (which can be programmed to any ford). On the forum you will find details about changing to a flip style key and focus style key. It depends if you're existing key has a glass chip or a carbon chip (later models had a carbon one). But someone will be along soon to help.
Hope this helps.
