E6400 post purchase queries

So I received my laptop just yesterday

I have been 'trying' to buy a laptop since months now. NBR has been my one stop source for all decision making. Wavered from 1330 to HP3005 to thinkpad to vaio SR But settled on E6400!

And there are some questions troubling me. I'll list them pointwise and it would be great if you people can help me out. I have installed vista myself.

1. Which drivers should I install for the quadro nvs 160m. I want to use it for some light gaming so naturally looking for any optimized drivers that would bring it closer to 9300. Looked on laptopvideo2go and downloaded a driver too but it doesnt install.

2. How do I turn off the bluetooth and where do I monitor, add, remove bluetooth connections from.

3. Which drivers should I download and install on priority. I dont have a driver disk and I dont want to install everything thats there on the dell site. Moreover its hard to make out which drivers are for which device. For ex. I still dont know which drivers to get for the fingerprint reader.

4. Why is the touchpad so **** slow. Do I need to install the drivers for that too?

5. How do I secure the DVD drive since its so easy to remove and walk away with.

A couple of things make me question the build quality. The right side of the battery is a bit loose. Also if there is a dvd spinning while I move the laptop even a bit it makes funny noise.

Thats about it for now. More queries as I face the problems.
