Thanks for the responses, I was looking at the Dom v3 and the Attitude V3 I do like the DVR capability, but the Quantum at that price is worth a look too.
What I was wondering was does the FC have any bearing on the setup, I guess no, the googles are just the goggles, and the real question should be about the camera and TX for the video, I just found minoposd on the wiki, I'll go read that 
Camera should be CCD for a couple of reasons. CMOS cameras often are cheaper, but have narrower dynamic range (hard to see in scenes with huge lighting contrast) and lower sensitivity (hard to see in low light conditions). Furthermore, most CMOS on the market use rolling shutter, which allows gathering a bit more photos, but also causes jello effect, edges get blured in situations when camera vibrates. For these reasons you should aim for CCD camera.
Camera should be also relatively low latency. The bottle neck is NTSC system 30fps which is roughly 33ms. So if your camera is much slower than lets say 50ms, I wouldn't recommend it.
The faster you want to fly the closer to 33ms you want to be. I guess it's a reason why FPV market still uses analog cameras. I would avoid Sony Effio-V chipsets. I use this cam, but I don't know if it's best one

Using proper antenna usually helps more than using stronger transmitter, as the range does not increase with the power of transmitter linearly. So you should be fine with 200mW vtx but it's good to have pair of polarized circular antennas (mushroom shape). Some people use patch antennas for more directional range, but I never tried, so can't tell how better that is.
Make sure you have at least buzzer installed before flying FPV. So many people lose vision and models
