H1 and AOS

My situation: I have applied for I-140 and I-485 as dependent and both cases are pending, and I am in Adjustment of Status. I have advance parole document approved, and I am planning a trip to China in coming Nov. I have not maintained my H4/H1 visa status while adjusting. Employer is applying for H1B1 for me now.

I got some questions:
1. Before H1B1petition for me by my employer is approved, whether my trip to China will incur the petition abandoned?

2. Whether I can return with approved AP if the H1B1 is pending?

3. When the H1B1 is approved, should I go outside of US to get visa stamp?

4. Whether the approval of H1B1 cause I-485 invalid?
Thanks in advance.
