Don't worry..... you are doing your best and this is good thing !!

Back to the homologation.... you should know that if you are a foreign citizen and your car have labels of your country of origin, you can drive that car in Italy without problems.

On the contrary, if you are an Italian citizen, you can drive a car with foreign labels for an year, if the title of the car says you are the owner (i.e. you go to USA, buy a car and then bring that car to Italy).

So fiirst of all you should tell us yor citizen and car's provenance.
