Verizon Fios Moca Network/Router and Premier XL4

I currently have Fios and 3 Verizon DVRs but am adding a Premier XL4. Since the moca network and moca router already assign IP's to my existing Verizon DVRs which provide the data to them can I assume I will not need a wireless adapter/ethernet connection since the Premier XL4 is setup for moca? Also I'm reading that I might need a filter...any feedback is greatly appreciated.
