Language / whats the easiest and fastest way to learn and understand Polish?? [6]

Czesc Everyone,

Well im in a bit of hot water here...
Two years ago I lived in Krakow for a year. This is where i met my lovely polka and who is now my wife. Unfortunatly I was very stubborn and didnt focus on learning Polish. Now we live in Australia and thinking about returning to live in a few years?

I NEED TO BECOME FLUENT IN POLISH!!. Plus to make things worse, my (polish) mother inlaw is learning English! So i need to learn as fast as possible.

PLEASE PLEASE HELP ME

I find it quiet difficult to study, not sure if i should do a course, private tutor, online lessons, download programs? I have used 'before you know it' which is quiet good. Does anyone have and sucessful ideas regarding learning this 'oh so hard' language????
