So you have an advantage to learning French. Which makes your job easier, you just need to learn a couple of exceptions, a couple of points where it differs (and if it really matters, when spoken I doubt one have to be anal about it and some leeway is allowed).
Which also means to understand and use French, you mostly have to learn words. As I suggested drill them, make cards or use an app. But since vocabulary as well isn't that alien, pronunciation is what you really have to train. From what I know about French, it's shit but at least they don't as inconsistent as English (although a lot uglier).
