First, watch doesn't exist. I deleted it from the man pages yesterday.

User is used to filter userspace originating audit messages. For example, you 
can use passwd and a message can be generated saying that a users password 
has been changed. You can filter those events so that they do not hit the 
audit logs.

auditctl -a user,always -F uid=500

Yes. But note that you can also do things like this:

-a exclude,always -F 'msgtype>=DAEMON_START' -F 'msgtype<=DAEMON_ROTATE'

to take out a whole range of message types.
