so if someone was sniffing with kismet on an open network they can see all of my traffic. But if I was connected to a secure network and they are logged onto it as well, can they still see my traffic?
1) Obviously, yes. Security is for people outside of the network, not for the clowns in it.
2) You should be posting this in here -> http://4-ch.net/tech/kareha.pl/1125953617/l50
