Dji phantom V2 plus

I want to order the DJI PHANTOM V2 plus Zenmuse 460000005-0. I have a Hero 3. What do I need to optimise its usability at reasonable cost ? Reading the comments maybe Fat Shark Attitude V2 FPV 253000027-0 ? One mentioned an Immersion EZ UHF 600? Can you recommend a list of what I need? Can I order everything if the Phantom is on back order and get it sent all together? Peter Birch
