Setting up Tivo Roamio on Time Warner Cable - TWC

I had a Tivo HD in the past on TWC, but we moved about a year ago and have survived without a Tivo since then. My wife has become quite vocal about not having it, so I ordered a Roamio Plus and a couple of Minis that will be here in a couple of days. I just want to make sure I'm not out of touch with what to expect. When I setup the Tivo HD back then, a truck roll was required, but seems thats no longer the case. I'll be using Coax for networking and have a couple of existing MOCA adapters already in the house.

Here is what I believe I need to do... fill me in if I missed anything.

1. I need to pick of an M Cablecard and Tuning Adapter from TWC.
2. Setup the Roamio and run it through guided setup before installing Cablecard.
3. Then install Cablecard and Tuning Adapter (with POE filter).
4. Call TWC Cablecard support to get it paired.

Is that it?

Thanks for your help.
