Family based I-485 cases are filed exclusively at local offices alongwith I-130. Filing of I-765 (For EAD) & I-131 (For AP) is optional. The receipt number given by local offices do not have a uniformity as compared to that issued by the service centers. You would not be able to check your status online for any of your applications (I-485, I-130, I-765 or I-131).
You may call the Customer Service # of CIS and they can give you approximate time taken by the local office (where you have applied) for each type of applications. There is no other way of knowing your individual application status without making a pilgrimage to the local CIS office and wasting your whole day.
Good Luck to all of us!
