You will most likely need to pull permits and have inspections at certain points due to having to electric wiring, etc. I know that sometimes even windows installed need to be inspected. Make sure you know all the codes and ordinances. I know that where I live, since we have a single car garage, we are allowed only a single car driveway and can't make it or the garage wider.

Yes, lots of different ways it could be done, depending on what exists......

Framing and building the side wall would not be hard, but hanging the garage door should be left to a professional.

First check your building codes. In my community some car ports were built and were ok as they are open. Closing them in makes them too close to the property line.
