Wondering if this is a good set up

[Moskino]

So im wanting to get my first fpv system..I have a phantom 1 with h3-2d with gopro 3+..I am not interested in range as much as getting very good feed..I am leaning towards a Black Pearl 7 CH Diversity monitor/ a immersion 5.8ghz 600w transmitter/ the 3 antennna fplvr kit..What else will i need? Will i need a separate cable for gopro to TX? How will TX get power? Will i need anything else if want to add iosd? Thanks for helping a fpv newbie...
