I would suggest getting the older model of Panasonic GF-1, unless you want higher HD video quality. Go for GF-2.
Please also, get the kit that comes with 20mm f/1.7 lens. You will find it a lot more helpful when taking photos indoor.
E-P2 has no flash. I don't think you want to carry a big flash with you every time you go out, at least not for me. I think you will find it a lot more "usable" with GF-1 or GF-2.
Why GF-1, the older model? Mainly because the manual switch on top of the camera. You can switch mode a lot easier and quicker.
Again, it depends on your use.
