I am not sure how to submit the two forms simultaneously online, but with paper they can send them both in the same bundle of paperwork.
2 - What forms should they use (the one for her parents and one that allows me to be their liaison with INZ for any communication) and how do we get these online so we can print them? (I have search high and low on the INZ site but can only find the option to apply online)
Submitting a paper application form remains possible according to the
relevant visa factsheet, for those who cannot or will not submit an online application.
The visa factsheet further provides two forms and one guide:

The aforementioned INZ 1018 guide should answer this.

Your parents must use a doctor or radiologist from INZ's
approved list of panel physicians.
If the panel physician is on INZ's eMedical system, they will (usually) submit the results to INZ directly. You will need to obtain an eMedical Reference Code (NZER) and fill this in on the application form.
If the panel physician is not on INZ's eMedical system, seek guidance from the panel physician on how the medical results are to be submitted.

I know they would have to send their passports here etc, but this is something we would consider also.
