UL30A clean install questions

I performed a fresh install with a retail Windows 7 disc (well, an MSDN WIndows 7 disc, but close enough). What utilities and drivers do I need to install to get the best battery life and performance out of it? So far, I've installed...

Code:

ATKOSD2
ATK Generic Function Service Utility
ATK Hotkey Utility
ATKACPI Driver
Latest version of the GMA driver from Intel's site
Alcor AU6433 Card Reader Driver (could this possibly be removed?)
Elantech Touchpad Driver
ASUS FastBoot
Power4Gear Hybrid
System Monitor Utility
Intel Matrix Storage Manager

Everything from ASUS' driver download site for the UL30 aside from the Intel driver where I noted. Is there anything else I should install? Also, Windows seemed to auto-detect the wireless, but where can I get the proper, latest driver for it? It's listed as "Atheros AR9285 Wireless Network Adapter" in the device manager.

I was also wondering if there was a way to control the amount of RAM dedicated to the graphics chipset.

Thanks.

 

Well, I just had to box it up to send in to ASUS for a replacement. There's a minor scratch on the screen that's bugging me.

I was also wondering, is there another place to get the audio drivers? ASUS' website is dog slow for me.
