You have a camera that has both Manual mode and image stabilization. You will have to use the manual mode in order to slow down the shutter slow enough to catch extreme low light situations.

As you know you will obviously need a tripod, choose something with atleast some ambient light, slow down your ISO to avoid noise, but lower your shutter speed as necessary. For you your driveway shots, I'd guess that would be atleast a sec or more.

You can also raise your ISO to 400 as your upper threshold to keep noise to a min. Any higher and you'll need some post processing to avoid what you got in the 3rd shot of the first set.

Play with the same shots using your shutter priority mode or manual mode. When you play with E/V, it only over/under exposes the shot. That's not what you're after. What George was talking about was your flash comp settings where you can +/- to try and mimick using an external flash with bounce or diffuser.

Good luck and just practice, practice, practice.
