Running iDeneb v1.3 10.5.5

I found more details about my hardware that can hopefully help. I've been looking around, but I'm still having a hard time finding the right way to get certain things to work. Hopefully some of you may have had the same hardware and know how some work arounds. Thank you.

CD/DVD Drive: MATSHITA UJDA775 DVD/CDRW ATA Device
Ethernet: Intel 82566MM Gigabit Network Connection
WiFi: Intel Wireless WiFi Link 4965AG
Audio: SoundMAX Integrated Digital HD Audio

Sleep doesn't work and the wifi package I installed from iwi has the icon in the bar, but won't find any networks. Constantly stuck on scanning.

Once again, any help is much appreciated.
