I am flying from Phoenix to Beijing. Is 2hours 25mins enough time for a layover in LAX?

My flight from PHX arrives at 11:15PM on US Air so I am guessing that is Terminal 1. My flight to Beijing departs at 1:40AM from Bradley on China Air leaving me with 2hrs 25mins for a layover. The ticket was booked on kayak.com so I'm not sure if it is a code share. Is that enough time to change terminals? Will I need to pick up my bags and haul them to Bradley or will they be sent to China Air? What is the shuttle service like between terminals? I will have 2 70lb checked bags plus carry on with me. It would be difficult to walk between terminals if my luggage is not sent to China Air for me. What is check in/security like at 11:30PM? Is security for an international flight similar to security for a domestic flight? Will I need to go through customs? This is my first international flight and I am very nervous. Thank you for any answers you may be able to provide. If you have additional tips or advice I would appreciate it!!!!
