US Immigration from Zimbabwe

After you get married and you are filing for AOS, are you supposed to include the Work and Travel Permit Forms in the entire package or are you supposed to send those out separately? I noticed there are different processing times on each of these, so I'm just making sure.

My fiancee is a citizen of Zimbabwe, but has lived in South Africa for several years. I requested that her case be sent to Harare since she is a citizen there, but it looks like they are sending it to Johannesburg instead. Since she is not a citizen of South Africa, will this affect her approval in any way?

I received my second NoA from the USCIS about a month ago and in the letter it said it would take the NVC about 2-4 weeks to process. Should I be on the lookout for some kind of confirmation in the mail or are they only sending the info to my overseas fiancee?

My fiancee is in Kwazulu Natal and with all the unrest going on over there, I'm legitimately afraid that she could starve there. Is it even a chance that I could ask to speed up the process?

I was looking on the Visa Guide and it says to print out a form I-134 Affidavit of Support. I printed it out from the link on this website, but as I was filling it out, I noticed it has an expiration date of 2/28/21. Does that make this form invalid?
