Severe financial loss?  Requesting an expedite is free.  I would certainly try it.  Just don't expect it to really mean "expedite" if approved.  Good luck.
Expedite Requests | USCIS

Actually, yes, they do.  It is recorded on your IRS transcript/account records. 

Severe financial loss to a company or person, provided that the need for urgent action is not the result of the petitioner’s or applicant’s failure to timely file the benefit request or to timely respond to any requests for evidence; he can try it

For future USCIS submissions, do not use credit cards. Personal checks or money orders are much more reliable.

Administrative processing is something that involves several agencies from what I have seen reported here. You try to do mandamus, they can come back and say not sufficient time to complete the checks, visa refused.  So think hard if and when you want to try that process for administrative processing. 
 
And BTW, he received approval of O-1 petition, not visa - visa is a consular process, petition is USCIS process. 

You don't need an EAD if you have a Green Card.  A Green Card holder has work authorization.

That is for all DL services.  Unless they have changed it, you can try for an appointment at 8:00 am every day.  If they have any openings, you can get one.  Otherwise appointments here in my area are booked for months.

Your spouse must be present. You will get asked more questions about marriage and your spouse to ensure it's bonafide.

Imo, she has been lucky.  The Carrier Information Guide specifically states: "Expired Conditional Resident Card, Form I-551 accompanied by Original Form I-797, Notice of Action indicating the card validity is extended".  The guide is not a USCIS document.  
 
"The U.S. Customs and Border Protection (CBP) Carrier Information Guide serves as a reference aid for travel industry personnel. It outlines the required documents that apply to persons entering or departing the United States. Carrier personnel are urged to familiarize themselves with all sections of the publication and reference it in their examination of travel documents."
My point is that, regardless of what USCIS says, there is a possibility she will be denied boarding.   Good luck on the rest of your immigration journey.  Next action for your spouse is either an I-751 interview or N-400 submission.

I found out exactly 2 days prior to my wife's N-400 interview that we would have a combo interview.  But, of course, I had been planning on a combo interview the entire time. 

I would not stay for the full time allowed.  Short visits are better. If CBP even thinks the OP is trying to live in the US on VWP, some very negative consequences can occur.  

Your Green Card will be taken away.....but NOT your passport.  I'm not sure why they would want to see it.  Make sure you take a black ink pen and the questionnaire as required by the instructions on the letter.  Congratulations!!

I have seen cases where a copy worked.  I have seen cases where it didn't work.  However, the official Carrier information guide says the original extension letter must accompany the expired Green Card:
 
Carrier Information Guide- English (cbp.gov)
 

I-90 extension letter

Foreign passport is a property of a foreign government and won't be taken away. Maybe it's for confirming any foreign trips between the interview and oath.

It usually takes 4-6 weeks after delivery to receive extension letter, so you're looking into mid May.
Also, don't forget, USCIS had tons of people applying before April 1st to lock in old fees and they're probably overwhelmed dealing with influx of petitions. It's totally normal.

With what extension letter was she using to board before?

Do you have physical watermarked extension letter? The first issue you may face is airline not accepting the printout and denying boarding. Some were lucky to board with copy but it's more of an exception than rule.

This is only meant as a gentle jab, but strap in cause it's a long ride in general.
If you get used to waiting, using the down times to research the next steps and collecting documentation, you'll be able to keep your sanity through it. Best of luck!

You will need I-864 for each of them and sealed I-693 Medical Exam
 

No, that is not the case for petition processing.  I-129fs go to the California Service Center while I-130s go to a particular service center based on USCIS workload and internal processes.  They are not assigned based on geographical locations.
