No. It will be on your cars age related plate and not the engine.
Silvertop or Blacktop. You might like to buy a cheap car and chop the rest in for scrap to make your money up.
Fine. Depends what flywheel option you go for.
Probably 1.8
GBS do some Zetec for the 2B unless you want to move the engine back a bit and reweld the Chassis in which case make your own.
As above
I would say something like a ZX9 set with a Megajolt is the easiest way.
Spiggot and release bearings depending on what you do with Clutch / Flywheel. I suggest using the Pinto Alternator as it's a bit smaller and plenty man enough for a bare Zetec, shortened sump (?), pedals (?), Pinto starter fits Silvertop with small mod to Sump, fuel pump, take the pulleys on and replace the water pump with a reverse direction (escort?) and fit a V wheel for belt.
That should be enough to get you started
