Oh and for the WiFi problem, it could be a 10.6.0 issue. Try ethernet or a USB stick to get 10.6.8 on there. A PC can download the update here for the USB route:

Doesn't matter what format the USB stick is, FAT32 or even NTFS would be fine to let the Mac see the DMG, and open up the update inside. DMG files are like ISOs, they contain their own filesystem inside.
