Really, the only thing worth getting in most cases is a decent antivirus and something to clean out your registry like CCleaner. Routers have built in firewalls decent enough to stop automated attacks, and no firewall you install is going to be enough to stop a manual attack by someone who really wants to get in. Anything that limits what peers you can connect to is going to be, at best, hours old and thus irrelevant.
Also, I have XP64 and Vista64 legit discs, a questionably legal copy of an XP32 Pro disc (it's a copy they distributed to employees to install it on all of the computers at TI), and a copy of 98SE that pretty much qualifies as abandonware at this point.
