If you mean the 2GB RAM upgrade, I would presume you can choose four extra 2GB Pines and five WiFi modules, yes. That should not be a problem (board limit is 10).

You need some sort of 5v 2a micro usb power supply and a hdmi cable. That's it.
If you want WiFi and/or Bluetooth, you could get the combined WiFi/Bluetooth module, but the Pine does have an Ethernet port built-in, so if you're happy with that, all you need is the power supply and hdmi.
(Note that the necessary power supply utilises more current than the average smartphone/tablet charger can provide)
