correct remove all unused ports (even though used ones can still be exploited but hey you need them lol) also try going behind a good firewall, not only the windows one ,try this one:
use it but don't turn off windows firewallCode:netbot.com.cn/en/version/48-1.html
also if you have moneyz buy the CISCO firewall it's quite expensive and not really worth it for a home network but if you really need it...
EDIT: also forgot one thing do often net stats to see if someone isn't connected to your network (run->cmd->net stat)
