Theres more in Vista to block besides the firewall. In the meantime did you CHECK this?

Also you should activiate the HIDDEN Administrator account so that you can set USERS as admin effectively. check the microsoft site for tips using vista, if you havent.
Also disable all addons in your ie browser... Make sure you have compatible addons like google tool bar for Vista... otherwise it will crash it.. like what you are talking about.
I could give you a list of sites ...but im sure you can search them out yourself when youre done just looking at the firewall.
