請教XIAOBAITU等專家 about my situation, Thanks ahead

I ed the NIW/I485 concurrently in Dec. 2003. I140 was approved in 5/2004, finger printer in 1/2005. Recently I call immigration office to inquire my case. the reply say my case still in name check. I used AP to go to China once in 2005, after back I applied the EAD to work because my I-94 was took by the customer. But today I happen to find the the follow words when I want to apply another AP in the instruction:
"If you are in the US and want to travel abroad, you do not need to apply for advance parole if 1) you are H1 temorary worker, or H4 and 2) a form I485 was filed on your behalf and is pending with the USCIS. However upon returning to United States you must present your valid H nonimmigration visa and continue to remain eligible for that status."
my question are

A) Do I need to apply AP this time ?

B)Whether did I still use my H1-B rather than my EAD in the past two years?

I have confused at all. Expect your kindly answer and advice.
