Of course it's sufficient.  What else could possibly be needed?

Correct, so any further answer would require knowing what you HAVE in the way of documentation.

Copies of the documents he was given when deported 

Based on OP , the I-130 was already approved and they are at DS-260 stage. 
 
OP, answer yes to both questions and provide details of the 2 day in detention along with being denied admission and expedited removal. 
 
Once he gets to the interview, you will know if there are any other issues 

Ban will be up in 7 months, and the I-130 isn't filed yet.  No waiver is needed.

Cant say never unlawfully present when you were ordered removed for what appears to be unlawfully present.  
 
Under what circumstances do none of these apply?  Looks like the more than 180 days if he got a 5 yr ban? At a minimum unlawfully present and ordered removed is yes.
 
Illegally entry is unlawfully present.  At least two of these are yes.

We used the taxpayer ID from her return in Ecuador. Edited to add: this was the number from box 6b of Form W-7. However, you may consider using the identification number from the document in part 6d of the W-7 instead?
 
The format for the document I sent is below (slightly updated after looking at the current IRS language):
 
 
Note that I actually did include the parentheses after the identification numbers specifying what each one was.
 
Hope that helps.

In case you haven't already done so, you might want to consult with a lawyer if an I-212 waiver might be required for your husband.
 

Yes

Looks correct.  The ban should be well past by the time the immigrant visa is ready to be issued.
