For your driving license, don't go for the international one it's not useful (and it's validity is less). It's the normal one that is recognized by French local administration (and French insurances). Just be sure that your licence validity is at least more than 1 year before your travel (it has to be valid to be use and converted). So you will be able to drive a French car with it but only for the 1st year of stay. You will have to convert it during the 1st year as soon as you get your 1st official 1 year residency card (this will take some months anyway, you will have a temporary status in the meantime).
CMLI French training has 6 levels if I remember well. You may not follow all depending the time you have and the cost. My Wife followed only one, but it was really helpful. They training was done by a Filipino who was a teacher in France for years, so the level was quite good. And you can ask explanations is tagalog or cebuano (what you can't do in France). But in your case I would try to follow more than 1 level so that you would not be fully lost as you may have to do more things alone when in France. In French administrations, they seldom speak English...
In which area of France will you reside?
Feel free to ask any questions, but better to go in the section European/World: Immigration/VISA Help & Information to avoid interference with UK related questions...
