If you have a good free firewall like ZoneAlarm free home for personal use, the firewall will block all rogue packets incoming and protect all your personal data from leaving your pc without your permission.
If you don't have a firewall, download the free home for personal use. http://www.zonealarm.com

Generally you can't. If someone is packet sniffing they are looking at all the packets that arrive at the computer running the software. There isn't a way for them to redirect all the traffic on the whole network to their computer, unless they have hacked into the router. If you are using a wireless home network, with a linksys router here are a few steps which may help:
a. change the password, the default is username: administrator, password: admin, change it to something, like a favorite color and the year of your first car (black1995)
b. turn on the encryption for the wireless, either WPA or WEP, it can be cracked but is a good start
c. turn on MAC address restrictions. each computer has a unqiue id number, turning on this restriction will prevent computers you don't know about from connecting to your network.
If you do these steps you should be able to sleep at night and not have to worry too much.
