What are the requirements and process for obtaining a Multiple Entry Visa (MEV) to Thailand for my wife and me?

I am from the states, have US passport. My wife is US perm resident, and has Nigerian passport. I'd like to get her a MEV for a 6 month trip in Oct. to Thailand.

I was looking at requirements, and how to get her a visa, and I found this online:

Visit the Royal Thai Embassy or Consulate closest to your residence in the US. (I guess they come out to PHX every month or 2 from LA, for 2 days)

Submit the required documents, including:

1. Completed visa application form <- which form is this?

1. Valid Nigerian passport with at least 6 months validity

3. One passport photo meeting specific requirements

4. Proof of sufficient funds: <- how much for 6 months?

Can it me in our joint bank account?

Bank statements showcasing your ability to support yourself during your stay in Thailand (amount varies depending on your planned duration and itinerary).

5. Proof of onward/return flight tickets <- really? I won't have any flight tickets yet.. 3 months in advance.

6. Proof of accommodation details <- Huh? We want to travel around, won't have this all arranged...

7/ Travel insurance policy <- OK

8. US Permanent Resident Card (copy)

9. Visa fee: Payable at the embassy/consulate in cash or money order <- anyone know what the fee would be?

Does the above look accurate? Any idea if the visa would be issued same day? How long does it take?

So as a US citizen with US passport, what would be the process for me, vs my wife?

thanks, this is sort of a special situation.
