I wouldn't install ZoneAlarm or any Norton products under any circumstances. Both products have caused OS problems (quite publically, on occasion) in the past.
Firewall products are generally overkill for most people. Vista's firewall is quite capable.
I'm extremely security consciouss (and clued up with regard to threat vectors) but I don't feel any need to install a 3rd-party firewall product. I grudgingly run F-Secure anti-virus, because I'm not the only user of my laptop and my girlfriend wouldn't know to not forward me dodgy malware-ridden emails.
If it were just me, my laptop, router and the internet, I'd sit behind NAT with no security software at all.
Knowing what not to click, that is the only foolproof security measure I know.
