Hey Dapy,
Oscar is right, you need to do ALOT of reading before you get some idea of what question to formulate. Another thing you can do is get really into your research, thing of various starting points and work with it, for instance if you wanna start with collecting data, do so, if you wanna formulate your methodology also do so... It kind sounds confusing but somehow you will find your way around it and come out with what you need.
The only way to clean up a mess is to just start!!!!
Another thing you can do is tell us more of the things you have found out, be more explicit about your ideas and maybe we can guide you through it... Sometimes you need an outsider to see the sense in chaos. Or if you have a collegue you can talk to about it would be good.
I found talking about the research to someone else helps too, that way, through your own thought processing you find your answers.

Good luck.
