CAT services can do all for you, it is a little confussing what you are asking for , as in change of address on your licence i gather it is a Spanish licence , and the request for social security numbers i gather you want an Autonamo for self employment, so i also gather you have padrons, and Spanish residencia, the road tax would normally be done through your Lawyer when purchasing you house if you have a bought house , as you see it is a little unclear why you ask the questions
hope this of help if you can answer what i have asked then i will be able to point you in the right direction to get all done
