Level and Center of gravity - basics

OK, I have been trying for a while now to get the basics working but seems to be unable to get it right, I guess I am not the only one struggling with this so some sort of detailed instructions will be helpful.

 

First of all. I have the quad copter set up for x-frame, tested all functions work ok, and it is kind of flyable in stabilize, but it behaves far from stable, I have tried loiter with almost catastrophic outcome, but I guess the advanced modes have to wait until it flies ok in stabilize first.

 

So what are the problems :

 

When taking off into hover it tends to go forward and right, after I stabilize it into hover with stick input, it looks ok, but releasing the sticks make the copter advance forward and also quite fast to the right.

 

I guess this has to to do with leveling and Center of gravity, and possibly ensuring that the frame is not "out of true", but how do I go about checking these parameters? I have leveled the copter on the floor, which I guess is "level", I have tried to lift the copter by the dome and the COG seems ok, I have eye-spotted the frame and motors and they all seem to be quite ok. What else can you do, or are there some tricks to go about fixing this? Or is there something wrong with the electronics in my copter? Any ideas? BTW running 2.049 for the moment.
