Connecting VOIP - Nighthawk M1 (MR1100)

I think you will need to contact your old ISP.

In the US, our phone numbers are portable, but that is different from being able to connect the phone to the old provider when we shift to a new ISP.  What happens here is that the phone number is transferred from the the old provider's network to the new provider's network.  

One problem you have is that you have no way to connect your landline phone to any provider's network right now.  If you can connect it to your old providers phone network (likely with an ethernet VOIP adapter), then that will resolve it.  If they don't allow that, you'll need to find a new provider who does have an ethernet VOIP adapter, and work with them to transfer your old number.

One thing you should ask about is emergency services - where is the call answered if you dial 000, and how does that person know where you live?

Also, with this setup your VOIP phone will use your mobile data, and you'll be paying for that as weil the phone service itself.

Do I need to plug my previous modem into the Nighthawk using a blue or yellow internet/Ethernet cable and plug my phone into the previous modem?

For sure that won't work. It's not just the issues you raised.  Your modem acted as a bridge between your old router and your ISP's internet service.  There's nothing to bridge your new router too, it connects directly to the mobile network.
