There is an obvious false positive, it is when a user or a program issues an id command, if you are using Mac OS X and do not have root activated (which you shouldn't), then you can safely ignored this alerts. About your other problem I am not sure. Normal snort configuration should be scanning your whole subnet. There must be something in the network config (a blocked switch?) not permitting it...

2) Last night I had a bunch of alerts pop-up which said
"ATTACK-RESPONSES id check returned root"; content: "uid=0(root)"
Snort's signature database said this was an indication of an attacker
gaining super user access to the system and that there are no known
false positives. The alert also mentioned that the source for the
attacks were port 80 on IPs belonging to websites I had open(Snort and
SANS) I ran netstat to check if the ports they were connecting to had
established a connection but none of the ports mentioned showed any
connections. I also NMAPped the machine and it showed only the expected
ports to be open.

You probably wouldn't worry about what people think of you if you could know how seldom they do.
