The current list looks pretty good man. I'ld just recommend tryin' to keep the lateset and greatest all the time. That's gonna be kinda hard though with all the diffrent sites to check. A few thing I'ld add,
3D Mark 2000 - 2001 really penalizes you if you don't have hardware support for certain test. 2000 is more leniant
ZoneAlarm - Free Firewalls are allways good. See if you can still get ver. 2.6 I've heard that 3.0 is buggy.
Ad-Aware -
http://www.lavasoft.nu/ - I run the ad aware and the refupdater to stay up to date and I don't run a home computer without it. I had a friend install it last night and he cought 107
diffrent piecies of spyware in his computer.
DirectX - Maybe the latest proven version. I think 8.1 is a little problematic for some people but 8.0 seems pretty good and stable.
I think that would round things out nicely man.
