Did you plan to change your name when you got married? If you did, then be aware that you are unable to get a new Philippines passport in that changed name.

If the DS 3025 is not marked complete then you need to complete the vaccinations and get a civil surgeon to prepare an I693a that you will include with the i485.
You prepare the applications to be able to stand alone. If mire than one application requires the same evidence then you will provide it multiple times.
Civil Surgeons are only in the states. OP wants to get this resolved before arriving so the best place in Philippines for this is SLEC and if they do the vaccines then no additional hoops or interaction with a civil surgeon required for AOS.
YouTube is not a good source of immigration information. No such thing as an RFE for the I134.
Manila really only cares about your income. If your salary is sufficient then document that and don't worry about anything else.
In the future just ask all Manila specific questions in the Philippines regional forum because answers can vary by consulate.
PS. Manila may not even want to see the i134 at all when the interview happens.
Depends on the how many interviews they do each month and the length of the queue in front of you.
2 to 3 months on average is not unusual but your consulate may not be average
