Advance Parole

I have been here on F1-OPT post completion (EAD valid from May 02, 2018 to April 02, 2019).
I applied for adjustment of status right after getting married in May 2018.

Here are the dates:
Application date: May 31, 2018
Receipt date: June 01, 2018
Cases applied concurrently: I-130, I-131, I-765, I-485.
The only update I got was for I-485 case with RFE on 10/19/2018. For rest of the cases I-130, I-131, I-765 there is no update, the online status only shows "my case was received..."

My questions are:
1) Is my I-131 advance parole delayed due receiving RFE for I-485 case?
2) I really need to travel to my home country, India ASAP (no later than November 15, 2018). How can I expedite the advance parole card?
3) I was told by many that the EAD/AP combo card will arrive within 120 days of the application, that is by October 1st, 2018. However, there is no update on my online status. How do I figure out if they are even working on my case or they haven't even started it?
4) The EAD card I applied based on F1-OPT earlier this year got approved in less 2.5 months. Now, why is it that the EAD/AP combo card taking forever? it been almost five months now.

Can someone help me in what to expect in my situation or what can I do to help myself?

Thank you!
