All working on Apple monitor now

Quake2 is now running without the artefacts too so i've had a good play on that tonight,
occasionally when quitting the game you return to the desktop and it's corrupted but a quick press of the sleep button and then again to wake seems to remedy that,
A few questions below:
Should i install a 9200 driver? I can see it looks like a 8500 in the extensions folder
Are there any programs worth updating or does the universal have latest of everything?
My USB disk though wouldn't connect - it asked me about formatting? Are there any fat32/ntfs drivers i can install?
I now have an airport, it does work but i need to turn my hotspot security off, i have seen some pci airport extreme compatible cards on ebay/amazon, is it worth getting one of those? I guess that will work out of box with 10.4.11 but will i need drivers for 9.2.2?
