The bus takes 40mins to 1 hour depends on traffic. Check Google maps for traffic. If you flight is domestic you need to be at the airport an hour before flight if international two hours. There is a bus every 30 mins from flyaway. So if I were you I will be there at 6:50 to take the 7:00 bus.
There are no stops. But depending on traffic it's about 1 hour ride. I would say no later than 6, the security lines at the airport can be insane at times.
Those buses do run every half hour and it'll take at least 40 mins or longer to get to LAX from the Van Nuys terminal.
